To the list you refer and also in the interests of completeness: full assent to all dogmatic Church teachings is also required for salvation.
This doesn’t mean every Catholic must understand them completely, at the level of a scholar; no level of “understanding” is required really (although of course encouraged)
Nor does it mean that if one is innocently ignorant of one, one is guilty of rejecting it. It does not mean that.
It simply means once one is educated about a dogmatic teaching, one cannot disagree with it. To know a teaching is dogmatic, and understand the teaching is dogmatic (which means it’s required) and to reject it anyway is a mortal sin.
So I guess that falls in line with Petrosius’ requirement # 3. I just thought it deserved its own mention, again for completeness.
“full assent to all dogmatic Church teachings” I guess that’s what I’m asking for as a list, what are all the things in the dogma of the Catholic Church that are required of an adherent to Catholicism for their Salvation? Are there things from the Magisterium or Traditions that are not on the list yet and need to be added?
