“So, how to you explain the Trinity without saying Three persons in one God?
Three beings in one God?
Hmmm. Wondering.”
Easy, learn to understand the Creed in Greek, or Syriac/Arabic, or Church Slavonic, or Latin (without the filioque as is normative for catechesis). The whole “person” idea comes from the Latin “persona” which means more a “mask” than “person”. The word to use is “hypostasis”, which is used even in English, thus three hypostasia in one ousia. Theologically, these words are used when discussing the Trinity in most languages because they avoid the problem of anthropomorphism.
St. Patrick’s shamrock is pretty good, too!
You got me there. Need to look up this word!
anthropomorphism
My personal favorite is the twisted pretzel - the kids in catechesis love that lesson because they get to consume it ;-)
