The Feast of the Holy Trinity

Today is the Feast of the Most Holy Trinity, the first Sunday after Pentecost. I've just learned that it was instituted in 1344, so it's way older than I assumed.

This is probably my favourite Sunday of the year because priests have to preach a doctrinal homily on Trinity Sunday.

I knew one priest whose Trinity Sunday homily was always about St. Augustine, trying to write a tract about the Trinity, walking along the seashore. He came across a child carrying water into a hole he'd dug in the sand, with a bucket. (Well, that was his version.) Asking him what he was doing, the child said he was trying to fill put the sea into the hole. Augustine drew the obvious moral.

So that's a bit of a dodge. But generally priests make an effort to preach something solid on Trinity Sunday.
