Let's practice with disputed question like: "Whether the Novus Ordo is the Catholic Church."

  • Everything that is one, holy, Catholic, and apostolic is the Catholic Church.
  • The Novus Ordo is one, holy, Catholic, and apostolic
  • ∴, the Novus Ordo is the Catholic Church.

In other words:
  • Every S is P.
  • Every Q is S.
  • ∴, every Q is P,
where S = "that which is one, holy, Catholic, and apostolic", P = "the Catholic Church", Q = "Novus Ordo". This is a classic BArbArA syllogism (cf. this thread) because all the propositions are universal affirmatives (A-type).

I could then reply: "I concede the major (#1) and distinguish the minor (#2). Some Q is S, and some Q is not S." etc.

See the What is strict syllogistic form? thread for more info.
