1) Theological and philosophical questions that are beyond RCIA-level are welcome here. (RCIA-level ones are fine for Catholicism 101; one point of this forum is to divert potentially confusing arguments away from those who already have enough on their plates.)

2) Rational argument on the above topics is welcome here.

3) Irrational argument is not, so please avoid name-calling, ad hominems, red herrings, and all other proof-substitutes.
