What is Valentine's Day

² This is what the Lord says:
Do not learn the way of the nations
or be terrified by signs in the heavens,
although the nations are terrified by them,
³for the customs of the peoples are worthless.
Jeremiah 10:2-3 CSB

In the 5th century, a pope "converted" the Roman festival of Lupercalia [3] to the Feast of Purification, which became our modern Valentine's Day [2]

The massacre I remembered is from 1929; it has nothing to do with the origin of Valentine's Day, though I've definitely had people bring it up when the date is talked about.
