I’ve been talking to a non-Catholic who’s asking about foundational Christian doctrine, the “non-negotiables” of Christianity, and where to draw the line on what is a basic doctrine (virgin birth, resurrection, etc.) and what isn’t (guaranteed salvation, etc)…
It wouldn’t be appropriate in the forum we’re in for me to come right out and tell him that the Church is the answer to what he’s seeking. I know this through experience.
So, I am guiding him to do some research on the Early Church Fathers, church history, development of doctrine, etc.
What could I recommend to him as a good starting point?
I’m thinking along the lines of Aquinas, Ignatius, and…?
Any help is greatly appreciated!
