Which dogmas have you had to defend in your lifetime?

[Kephapaulos]

I do not want to boast or cause anyone to boast about this because all the glory is to go to our Lord God when defending the Truth.

One was no salvation outside Catholic Church where I debated over the fact that Protestants are not in the True Church. I understand better now though that that is objectively so.

In recent times, I have had to defend the dogma of the perpetual virginity of Our Lady and of purgatory.

[Geremia]

I've had to defend against religious indifferentism, which could be considered a subset of extra Ecclesiam nulla salus.
