A short while ago I mentioned reading old stuff, so here’s a suggestion: reading the church fathers during Lent.
I grew up in an ahistorical form of Christianity and it was refreshing for me to learn that truly God doesn’t leave Himself without witness. The Holy Spirit was at work long before 1900, albeit using flawed human beings.
The readings start on Ash Wednesday (the 13th) and run from Monday through to Saturday. If you’re short on time, there’s a lite version. Happy reading!
