Wonder Woman, which by all accounts is the first great movie of the new "DC Universe.") Well, when we talk about abstract concepts like the Trinity we grab any metaphors that people can relate to.
The minister didn't dwell too long on the Father, Son, and Holy Spirit---in the modern world if you can't explain it in 144 characters or less, why even try---but did say that it was a mystery over which scholars had debated for centuries. Yes, your humble blogger remembers the Sunday School lessons about Trinity--three aspects of the same God, none greater than the other--but that's about the extent of it.
I stopped trying to understand when all references to "Holy Ghost" were changed to "Holy Spirit" throughout the Liturgy in the 1970's. From the comics (see how I brought that full circle) I knew that there was a big difference between a ghost and a spirit; if the church can make such a word change so blithely, I knew deep theology wasn't my forte.
At least they didn't change the great hymn of Trinity Sunday.
