I think my favorite day of the year might be Trinity Sunday.
It’s not obvious, except that every year it makes me gasp and be happy. I probably like it better than other feasts because there’s never any obligatory feasting involved, thank goodness for that.
I don’t have anything to say about the Trinity. The Catechism does have some things to say, and those will keep you busy for a while.
Meanwhile, here are some icons of the Holy Trinity.
Photos taken just after dinner, I guess.
You get pictures like this to explain the unfathomable if you’re from the mystic eastern lung of the Church; in the west, we prefer bad analogies, of course. It’s good of the Church to call this Trinity Sunday and not Struggling With Theology Sunday.
But you can have a pretty good feast day if you pick one known true thing about the Holy Trinity and for a few minutes let it sit in your brain unfixed. This is the thing with mysteries: They are meant to be worked at. They are meant to be announced and examined and slowly revealed, bit by bit, until in the fullness of time our thirst for understanding is satisfied.
