The Thomist 67 (2003): 157-95 THEOLOGICAL PRINCIPLES THAT GUIDED THE REDACTION OF THE ROMAN MISSAL (1970) 1 LAUREN PRISTAS Caldwell College Caldwell, New Jersey I N THE LAST THREE DECADES there has been much discussion, even heated debate, about the liturgical texts currently in use, or proposed for use, in English-speaking countries. Articles in the popular press and in scholarly journals have centered almost exclusively on the texts produced by the International Commission on English in the Liturgy (ICEL)-that is, on the quality of translations, the linguistic theories undergirding them, the competence of a mixed commission to compose original texts, and the respective roles of the bishops' conferences and the Holy See in approving vernacular translations. 2 These matters are vitally 1 I am grateful to the Intercultural Forum for Studies in Faith and Culture at the Pope John Paul II Cultural Center, Washington, D.C., for the support that enabled me to complete this article. 2 See, for examples, Robert Speaight, "Liturgy and Language," Theology: Monthly Review 74 (October 1971): 444-56; Ralph A.

Krosnicki, Ancient Themes in Modem Prayer (Washington, D.C.: The Catholic University of A.merica Press, 1973); Anthony Cekada, The Problems with the Prayers of the Modem Mass (Rockford, Ill.: Tan Books and Publishers, 1991); Gerard Moore, Vatican II and the Collects for Ordinary Time: A in the Roman Missal (1975) (San Francisco: The Scholars Press, 1998); Lorenzo Bianchi, "A Survey of the Theology, Historf, Terminology and Synta'L in the Prayers of the Roman Missal," in Theological and Historical Aspects of the Roman Missal, The Proceedings of the Fifth of Historical, Canonical and ne«i)logica1 Studies on the Roman International Catholic Liturgy (Kingston and Surbiton: Centre International Liturgiques, 2000), 127-64. 4 The alphabetical listing of all the orations in the present Roman Missal in Thaddaus A. Schnitker and Wolfgang A. eds., Concordantia verbalia missalis romani: Partes euchologicae (Miinster: Aschendorff, 1983), col. 2865-2910 contains 1,479 orations, exclusive of blessing prayers. Annibale Bugnini, The Reform of the Liturgy (1948-1975), trans. Matthew J. O'Connell (Collegeville, Minn.: The Liturgical Press, 1990), 396 states that the new missal has "sixteen hundred prayers," which must be a round number that includes all the blessing prayers. Matias Auge, "Le collete del proprio de! tempo nel nuovo messale," Ephemerides Liturgicae 84 (1970): 275 states t.hat the new missal has "about two thousand prayers" (duemilla preghiere circa), a nu..mberthat, based on Schnitker's list, is hard to explain. Both Bugnini and Auge state that the number of orations in the new missal is more than twice the number in the 1962 Missal. 5 That is, the last edition of the Roman Missal prior to the reforms mandated by Vatican H. The 1962 Missal is the last typical edition of the Missal of Pius V, also called the Tridentine Missal, which was commissioned by the Council of Trent and first appeared in 1570. THE REDACTION OF THE ROMAN MISSAL (1970) 159 sacramentaries or collections of liturgical formularies; still others are new compositions. Many of the orations that were taken from earlier missals or codices were edited. The newly composed texts are woven from threads of two or three ancient orations; constructed of phrases from biblical, patristic, or ecclesiastical texts; or composed in their entirety by those who produced the new missal. Therefore, many of the orations of the Paul Missal are not ancient prayers in the strict sense, but modern redactions of ancient prayers or entirely new compositions. At the time the new missal appeared, those involved in the work of the reform published articles in v.rhich they set forth the principles that guided selection, arrangement, redaction, and creation of texts, and explained how the principles were concretely applied. 6 Frequently they offered examples. These articles have received little scholarly attention though they are great reservoirs information about the practical decisions made by the reformers. Because these decisions were often subjective, of a new generation. they invite reappraisal by competent More important, however, than scholarly evaluation of the particular judgments, even those with widespread application, is the objective review of the philosophical and theological principles that drove the reform. This has not been undertaken. A thorough evaluation of these principles distinguish those from those embraced by the stipulated by the council Consilium 7 the course of the revision process, and evaluate the See, for example, Henry Ashworth, "The Prayers for the Dead in the Missal of Pope Paul VI," Ephemerides Liturgicae 85 (1971): 3-15; Auge, "Le coliete del proprio de! tempo nel nuovo messale," 275-98; Carlo Braga, "II nuovo messale romano," Ephe>.

Like other Aristotelian translations mthis essay, this one is &om the Revised Oxford Translation (Barnes, ed.), occasionally (as here) slightly revised, The translation of GA has as its base an earlier translation by A. Platt, who translated To icu11µa in line 736a32 (and ;a Kutjµam at 736b9 and '736b11) as "unfertilized embryo." Berti takes exception to this translation (Berti "Quando esiste l'uomo in potenza?", 117); it does not appear in the Barnes version. 8 Berti, "Qoondo esiste l'uomo in potenza?", 117. 9 Ibid., 118. 10 Ibid. APPLYINGARISTOTLE IN CONTEMPORARY EMBRYOLOGY 253 Satisfied that Aristotle is saying in GA 2.3 that right from the beginning the embryo is possessed of a nutritive soul in act and the other two souls in potency, Berti introduces the passage from De an. 2.3. His intention in doing so is to show that the type of potency attaching to the rational soul is such that we can say that the rational soul is present in the embryo right from the beginning. The cases of figure and soul are exactly parallel; for the particulars subsumed under the common name in both cases-figures and living beings--constirute a series, each successive term of which potentially contains its predecessor, e.g., the square the triangle, the sensory power the self-nutritive. Hence we must ask in the case of each order of living things, What is its soul, i.e., What is the soul of plant, man, beast? ... For the power of perception is never found apart from the power of self-nutrition .... Again, among living things that possess sense some have the power of locomotion, some not. Lastly, certain living beings-a smaH minority-possess calculation and thought, for (among mortal beings) those which possess calculation have all the other powers above mentioned, while the converse does not hold .... Reflective thought [Si:wp11n1<(x_; presents a different problem. 11 It is dear, notes Berti, that Aristotle holds that in any living being there is just one souL 12 In human beings, that soul is rational; thus, when Aristotle says GA 2.3 that the rational (and the sensitive) souls are in the embryo in potency, even at that point we must assume that the real soul is the rational, that it contains the other two (or, at least, the corresponding faculties). To quote Berti, "Here, as one sees, Aristotle affirms that the superior soul contains in itself the inferior, and not vice-versa. Thus, in the human embryo, one must suppose that there is already contained the soul superior to all, i.e., the rational, which however possesses in act only the nutritive faculty, and in potency the sensitive and rational. " 13 Berti also acknowledges that, for the rational fac. .dty to be to operate, there is required intelletto teoretico flE Kai µna!'kXAA£1v),OTCTV r:; i\811 l'i1a Tfj<; athoO apxfi<; TOIOUTOV, ijori TOUTO 8uvciµn.

The word nEcrElv is inserted by Ross; in the Jaeger text it does not appear (nor is it tnnslated in the Barnes volume [p. 1656]). Since Berti's translation presupposes n£crdv, for the moment I use Ross's older translation of Metaph. rather than the Barnes revision. 17 Berri, "Quando esiste l'uomo in potenza?", 121. 256 KEVIN L. FLANNERY,S.J. referred to (where he speaks of both the semen and the embryo as "not yet separate") but also at the beginning of the passage: "since both the semen and the embryo [Ta TE 01TEpµaTa Kai Ta KutjµaTa (736a33-34)] of animals live no less than those of plants." It is only at the second stage, with respect to which Aristotle mentions the embryo and not the semen, that we have that which "absorbs nourishment and performs the function of the nutritive soul." This is the embryo that has become "separate" from the mother, in the sense that it has bodily integrity and movement of its own. 18 This is consistent with what he says elsewhere in GA, where the embryo requires some time in the presence of the semen--or, more precisely, in the presence of that which it brings: its pneuma-before it launches out on its own. During this time the pneuma is working upon the embryo, but in an external way-that is, in such a way that the embryo cannot be said to have its own "motive principle" or dpxtj and therefore cannot be a man in first act. In GA 1.21and22, Aristotle insists that in the life of the early embryo the action of the pneuma is external. At the beginning of GA 1.21, he asks a number of crucial questions about the relationship between the semen and the menses (the female contribution to animal generation). 19 He wants to know "how it is that the male contributes to generation and how it is that the semen from the male is the cause of the offspring"; and he asks: "Does it exist in the body of the embryo as a part of it from the first [trOTEpovw<; EVUTTclpXOVKai µ6ptov ov Eu0u<;],mingling with the material which comes from the female? Or does the semen communicate nothing to the material body of the embryo but only to the power and movement in it?" (GA 1.21 [729b2-6]; emphasis added). His answer is quite emphatic: "the latter alternative appears to be the right one both a priori and in view of the facts. For, if we consider the question on general grounds, we find that, whenever one thing is made from two of which one is active and 18 See GA 2.1 (735a20-22); 2.4 (740a37-b2); 2.6 (742a2-3); 2.7 (746a22-28). At GA 2.4 (739a7-8), Aristotle notes that there is a part of the menses that is less fluid; see also 2.4 (739b26). So the female contribution is not just any part of the menses. 19 APPLYING ARISTOTIE IN CONTEMPORARY EMBRYOLOGY 257 the other passive, the active agent does not exist in that which is made" (GA 1.21 [729b8-11];emphasisadded). He acknowledges, of course, that the formation of the embryo does take place within the female, not the male (GA 1.22 [730a32-bl]); but even this, he says, can be accounted for in terms of his standard examples of crafts: "the carpenter must keep in close connection with his timber and the potter with his clay, and generally all workmanship and the ultimate movement imparted to matter must be connected with the material concerned, as, for instance, architecture is in the buildings it makes" (GA 1.22 [730b6-8]). A craftsman nonetheless always remains external to his artifact (see Metaph. 9.7 [1049a11-12]). In GA 2.1 Aristotle comes back to this issue, suggesting at first that the operation of the semen must be internal to the embryo: "Now it would appear irrational to suppose that any of either the internal organs [O'lTliayxvwv(734a2)] or the other parts is made by something external, since one thing cannot set up a motion in another without touching it, nor can a thing be affected in any way by anything that does not set up a motion in it" (GA 2.1 [734a2-4]). (The parts of the body mentioned here would include the so-called homoeomerous parts such as blood, flesh, and the material of bones. )20 After mentioning some possible objections, he says that it is necessary to make some distinctions; in particular, we must determine in what sense it is impossible that the parts might be generated by something external (GA 2.1 [734b4-7]): "For if in a certain sense they cannot, yet in another sense they can." It is possible, then, that A should move B, and B move C; that, in fact, the case should be the same as with the automatic toys. For the parts of such toys while at rest have a sort of potentiality of motion in them, and when any external force puts the first of them in motion, immediately the next is moved in actuality. As, zo See GA 1.1 (715a9-l 1): mwrl. µ£v T«jl OAfp Ta dvoµotoµEpfj, o' dvoµotoµEpfot Ta 6µo1oµepfj, of: Ta Ka>.oUµeva0T01xda Tuiv owµucrt::w<; dpxfiv Kal TEl.o<; (742b1)], this must be the first to come into being-first, that is, considered as the moving power, but simultaneous with the whole embryo if considered as a part of the end" (GA 2.6 [742a37-b3]). Putting all these ideas together, the scheme that forces itself upon us is one in which the animal embryo has initially the life of a plant, although with this difference: a plant has an internal motive principle, whereas an embryo is moved along by the continued action of the semen, which is only internal in the way that the motion of automatic toys is internal. Eventually, however, the principle of the animal's own nutritive life is constructed out of the material provided by the mother. This principle is the heart. Aristotle very clearly associates it with the animal's nutritive life in lines coming shortly after the longer passage just quoted: Therefore it is that the heart appears first distinctly marked off in all the sanguinea, for this is the first principle [cipxiil of both homoeomerous and nonhomoeomerous parts, since from the moment that the animal or organism APPLYING AR1STOTI.E IN CONTEMPORARY EMBRYOLOGY 261 needs nourishment, from that moment does this deserve to be called its principle [dpxtjv (740a19)]. For that which exists grows, and the nutriment, in its final stage, of an animal is the blood or its analogue, and of this the blood-vessels are the receptade, and that is why the heart is the principle of these also. (GA 2.4 [740a17-23]) We are not therefore to associate the nutnt1ve life of the animal with the nutritive life one sees in the early developing embryo. The former is related more to plant life, and the nutritive faculty in animals is quite different. As Aristotle says in De an. 2.3, "It is ... evident that a single definition can be given of soul only in the same sense as one can be given of figure .... Hence we must ask in the case of each order of living things, What is its soul, i.e. What is the soul of plant, animal, man?" (De an. 2.3 [414b20-33]). It is true that the nutritive faculty of a plant can be said to fall under the same definition as the nutritive faculty of man, but this would only be a logical definition: the nutritive life of a plant is radically different from that of a man (similar to the way that a triangle is radically different from a square). 23 fact, it is difficult even to say that the early embryo has a nutritive soul, although it does, as we have seen, "seem to live the life of a plant" (GA 2.3 [736b12-13]). Immediate after the passage about the automatic toys in GA 2.1, Aristotle says of the pneuma, "Plainly, then, while there is something [i.e., the pneuma] which makes the parts, this does not exist as a definite object [TobE Tl], nor does it exist in the semen at the first as a complete part. " 24 If the early embryo had a soul, it would inform its body and together they would constitute a TObE n in such a way that also the form could be said to be a TOSE n (see Metaph. 7.3 [1029a27-30]). As things are, according to Aristotle, the pneuma never really enters into the material presented by the mother. genuine Toa£ n-and a 23 See Thomas Aquinas, Quaestio disputata de spiritalibus creaturis, a.1 ad 24: "Anima autem alterius animalis dat ei solum esse animal; unde animal commune non est unum numero, sed ratione t:anturn; quia non ab una et eadem forma homo est animal et asinus."

Therefore the heart is first differentiated in 2A [740a2-4]; see also he says that the [666a20-23]), Two chapters followed immediately by head: "that part which first principle comes into being next to this the This is the parts about the head, particularly the eyes, appear largest the at an early stage, while the the umbilicus, as legs, are small; for the parts are the sake upper, are neither parts of the end nor able to 2.6 [742b12-17]). various functions of the animal So, the organs necessary for appear more-or-less at the same time: the heart first, but head and the eyes follow thereupon. have already seen that the is associated with nutrition, but it is also up with sensation: ..the motions of pain pleasure, and generally of all their source in the heart, and find in it sensation, their ultimate termination" 3A [666a11-13]; see also GA 2.6 [742a32-33], regarding locomotion). Indeed, as we have already APPLYING ARISTOTLE IN CONTEMPORARY EMBRYOLOGY 263 seen, the heart is in animals the "principle and end of all their nature" (GA 2.6 [742b1]; emphasis added). And the organ corresponding to the sense of touch is the body itself (GA 2.6 [743b37-744a1]), which would seem to have its human beginning simultaneously with the heart. This is all evidence in support of Berti's thesis that the various faculties arrive at one time. Even if the primary sense organs appear after the heart, the heart is involved not just in nutrition but also in sensation. As for the rational part, since it requires no physical organ (although in men it presupposes the sensitive functions), there is no difficulty locating its inception also at this beginning, that is, when the heart is first formed. This would be consistent with Aristotle's remark in De an. 2.3, comparing the functions of the soul to geometrical figures: "for the particulars subsumed under the common name in both cases-figures and living beings--constitute a series, each successive term of which potentially contains its predecessor" (414b29-30). 25 The present interpretation also partially supports Berti's use of Metaph. 9. 7, regarding the embryo as first act. This becomes more apparent, however, if we make a slight revision to the text that Berti gives us. In his translation, the seed is said not to become 25 It has been suggested to me that Aristotle's remark at GA 2.3 (736b2-3), where he says that the embryo does not become at the same rime animal and man nor animal and horse counts against the thesis that all the faculties arrive at one rime. But it seems to me that that passage is talking about the eventual development of things already contained in potency (i.e., first act) within the embryo once the heart has developed. Aristotle says just after the remark about being animal then man, animal then horse, "For the end [To TiAcx;] is developed last, and the peculiar character of the species is the end of the generation in each individual" (GA 2.3 [736b3-5]). But surely the end is the natural consequence of that which the animal already is. Later on in GA, Aristotle makes clear what he means by saying that the fully specified animal arrives only later. He has in mind monstrosities that develop only up to the point of what is most general since the material of the embryo is not fully mastered by the movements that continue the development of the various organs (GA 4.3 [769b11-13]). "Then people say that the child has the head of a ram or a bull, and so on with other animals, as that a calf has the head of a child or a sheep that of an ox" (GA 4.3 [769b13-16]). But Aristotle will have none of this---clearly because he knows that the human monstrosity is still human: as he notes, the misshapen heads are just similarities such as happen naturally also when there is no deformity. That the complete development of the embryo regarding sexual differentiation and other characteristics, including possible monstrosity, depends on the heart can be gathered from GA 4.1 (766a30-b4); and 4.3 (769b3-10). 264 KEVIN L FLANNERY, S.J. a man in first it is first "deposited [undergoes] a change."

But when through its own motive principle it has already got such and such attributes, in this state it is already potentially a man; while in the former state it needs another motive principle. 9.7 [1049a14-17]) Ross argues that here "is not account own view the an£pµa forms no part of the matter the offspring is its formal cause"; 28 another explanation that Aristotle is using the "'seed" Metaph. the generic sense does not exclude the female contribution or embryo itself. 29 any case, the passage the nEcrr1v no longer suggests that the cmdal moment the seed fails onto the menses it more must "undergo says a change" -sometime or anothero This moment is to associated the first presence this latter is to be associated which becomes esiste l'uomo in potenza?", 118.

Can Ford call thesis that the human individual is not Aristotle support of present at conception? In a way yes, a way no. In order to understand the impact of Aristotle's embryology (both biological and metaphysical) on Ford's theory, we need to understand why Aristotle puts the onset of the motive principle at forty days (or so) rather than earlier. Let us go back to Aristotle's "crucial questions" asked at the beginning of GA 1.21 about the relationship between semen and menses. As we have seen, he says there that we must ask how it is that the male contributes to generation and how it is that the semen from the male is the cause of the offspring. Does it exist in the body of the embryo as a part of it from the first, mingling with the material which comes from the female? Or does the semen communicate nothing to the material body of the embryo but only to the power and movement in it? (GA 1.21 [729b1-6]) It may not be immediately apparent, but in this passage Aristotle is peering down the aHey where eventually genetic theory was to be discovered, and turning away for lack of light. He is asking whether there is something physical in the male semen that combines with the female element to form the embryo. He has in mind theories of his day, collectively known as "pangenesis," according to which the semen contained something drawn from body that would, after copulation, grow into a every part of full-sized animal. 30 Its advocates sometimes spoke a small 30 Aristotle offers a succint definition of 'pangenesis' at GA 1.18 (724a12-13): O:rro TiavTwv arroKpivnm To cmipµa Twv µopiwv. He tells us at GA 1.18 how his own approach differs from this: "For whereas they said that semen is that which comes from all the body, we shall say it is that whose nature is to go to all of it" (oi µ[v yap TO arro rravToc; amov, i'jµdc; OE TO 266 KEVIN L. FLANNERY,S.J. animal (l;4>ov µtKp6v [722b4-5]) (or, in humans, the so-called homunculus) passed along in the semen. 31 Aristotle had no evidence that there was any such object in the semen, nor any such resulting articulation in the embryo itself, up until at least the fortieth day. Until that point, he says, the embryo is "fleshlike" (KpEWOE<;, HA 7.3 [583b10-11]), which puts it among the homoeomerous parts (Mete. 4.10 [388a16]; PA 1.1 [640b18-20]). It is "without distinction of parts" (avap0pov, HA 7.3 [583b9]). Aristotle does say that within the female element are found all the parts of the animal in potency (GA 2.4 [740b18-21]), even those that distinguish the sexes (GA 2.3 [737a24-25]); but this must mean that they are found in potency the way that a bed is found in potency in the wood that stands before the carpenter, for Aristotle denies elsewhere that sex is determined at conception (GA 1.18 [723a23-b3]; 4.1 [763b26-27]). For him, sex differentiation depends upon the strength of heat in the semen (GA 4.1 [766a16-22]), which goes to work on the menses, only eventually producing organs, as we have seen. Most interestingly, there were theories available in the intellectual culture within which Aristotle worked that, at least in npOi; ruravr' ifvm 1TE$UKOi; arrepµa (po()µEv) (725a21-23). In fact, Aristotle propounds his own version of pangenism in GA 1.19. He says that semen is "a residue of the nutriment when reduced to blood, being that which is finally distributed to the parts of the body" (726b9-11); then he says, "for this reason also it is natural that the offspring should resemble the parents, for that which goes to all the parts of the body resembles that which is left over" (726b 13-15). But he immediately places these ideas within the context of his own theory, speaking of potency and indeterminacy (726b15-19). One finds a version of pangenesis also in Darwin: see A. L. Peck, trans., Aristotle, Generation of Animals (Cambridge, Mass., and London: Harvard University Press, 1953), 50 n. a. 31 That such theories of "pangenism" are on his mind in GA 1.21 is apparent from his use of the same (spurious) example to refute both pangenesis and this later idea that the semen contributes something physical to generation. I mean the example of certain insects whose females, during copulation, supposedly extend part of themselves into the male rather than vice-versa; this allows them to extract the ouvaµt<; from the male without any matter. According to Aristotle, this shows that also in cases where the male injects semen into the female the important thing is that he transfers Mvaµt<;. The example occurs both at GA 1.18 (723b19-27) (as an anti-pangenism argument); and at GA 1.21 (729b22-25) (as an antiphysical-contribution argument). Indeed, in the former argument (at 723b27}, he makes a forward reference to the general argument in favor of the notion that the male contributes nothing physical. See also GA 1.18 (724b4-6 and 724b23-30). APPLYINGARISTOTLEIN CONTEMPORARYEMBRYOLOGY 267 certain respects, come closer than his own to modern genetic theory. Aristotle himself is our best source regarding these theories. He recounts, as we have seen, that "some say that [the semen] comes from the whole of the body" (GA 1.17 [721bll12]). (Since some such thinkers were open to the idea that semen was produced by both parents [GA 1.17 (721b6-8)], "semen" here need not mean male semen.) One of their reasons for believing this was that children resemble their parents: "for the young are born like them part for part as well as in the whole body; if then the coming of the semen from the whole body is cause of the resemblance of the whole, so the parts would be like because it comes from each of the parts" (GA 1.17 [721b20-24]). Since the semen comes from all parts of the body, it would contain somehow all the traits that are passed on to the children. Empedocles even had a theory that exploited the idea of a part corresponding to a companion part, the two contributing to the whole progeny; he held, that is, that "there is a sort of tally in the male and female, and that the whole offspring does not come from either, 'but sundered is the fashion of limbs, some in the man's,
