There is a good book from St. Augustine. It is the response to those that blamed Christians for the fall of the Roman Empire—apologetics. I wish I could have read it all, but the lingo was above my edumication level, and that’s saying a lot since it was written so long ago.
In a gist, soon after Rome converted to Chrisianity, the empire crumbled. They had a lot more to go on than the current crisis we face. My personal opinion is that we face just the opposite...the decline in submission to our Creator combined with immorality (i.e., homosexual marriage).
Hopefully, people’s eye open up and put God back in charge with a desire to make ammends.
St. Augustine’s book is, “City of God.”
