this thread is for you ALL!

Come share the cool stuff you love about the past!

We do not allow posts based on personal or relatives' anecdotes. Brief and short answers are allowed but MUST be properly sourced to respectable literature. All other rules also apply—no bigotry, current events, and so forth.

For this round, let’s look at: Christianity! From lesser known figures to how it spread around the world, this week's post is your place to share all things related to the Father, the Son, and the Holy Ghost.
