I found a site that list a lot of good, i think, classical book about Christianity.
I was searching “The Incarnation of the Word of God by St. Athanasius”, which was
a required reading for my seminary class. I learned two things.
First, there are lots of classics that I would be interested in reading.
For my spiritual reading I have been reading just contemporary book including C.S. Lewis whom
I thought his book can be considered as classic. However, give around 2000 years of Christendom history, there should be a lot more classical book than C.S. Lewis.
This site would give me a good starting place to get familiar with Christian classic.
I may not be able to read all of them, but at least would know there are lots of classics like these.
