The vast majority of Christians do not grasp the Trinity, and they don t really have to. Faith in the Creator is enough.Folks who poo-poo the Trinity fail to understand that it answers the problem of an eternal being existing ontologically prior to all other existents, as well as the subject-object problem, the one-and-the-other problem. Of course God is an eternal Relationship of Agreement!I liken the trinity to body, mind and soul.
But some of us are obsessive and some are even Autisticly obsessive and so we dive into waters that are dark and still and may harbor who knows what?
But nonChristians mostly just laugh at our semantic wrangling. Their loss, really.
Just another version of polytheism.
