Kreeft is a Catholic professor of philosophy and does much work in Christian apologetics. Listening to him he seems to have a humble and instructive spirit about him which I quite enjoy. The follow texts he suggests are not all by Catholic authors, only a handful are.
See the full lecture from which this list is derived at https://www.youtube.com/watch?v=bLm5RggbhlE&list=LLu0lqitLzCtL1eZkAAMuQCQ
Kreeft has authored several books as well.
He selected these to be not too difficult but difficult enough to be challenging.
The material in parenthesis are also analysis and commentary by Kreeft from the lecture.
Above all of these, he says The Bible is the best book!
A few mentions from Kreeft:
The greatest discoveries are found by asking dumb questions
You can’t force one to cry. Tears mean it’s a great author.
The job description of a great artist is to break the human heart.
He likes short books.
