1) If you think the Trinity represents three gods, you don’t understand the doctrine.
Christian theologists call the Trinity doctrine "a mystery in the strict sense" in that it "cannot be known by unaided human reason apart from revelation, nor cogently demonstrated by reason after it has been revealed" (
Oxford Dictionary of the Christian Church, with which the online Catholic Encyclopedia, in rather less direct words, agrees).
It will only take you a moment to notice that anything which answers that description would usually be called "a nonsense" in polite society, while other synonyms may be found elsewhere.
The Trinity doctrine is not only not found, but expressly denied, in the NT. Paul, and each of the Jesuses of Mark, Matthew, Luke and John expressly denies he's God and never once claims to be God. The doctrine is devised in the 4th century CE to satisfy Christian political pressure to promote Jesus to God status ─ but without opening the Church to the charge that like the pagans, they're polytheists.
Therefore the doctrine declares that the Father is not Jesus or the Ghost and is 100% of God, Jesus is not the Father or the Ghost and is 100% of God, and the Ghost is not the Father or Jesus and is 100% of God. It will already have occurred to you that 100% + 100% + 100% = 300% = three gods, and the only thing that stands between us and the obvious is the doctrine's declaration that this isn't so in this case because it's "a mystery in the strict sense" instead ─ which as I said above, means it's a nonsense.
It doesn't explain, when you pray to God, who answers the phone; nor why the Jesuses of Mark and Matthew should say on the cross, "Me, me, why have I forsaken me?"; nor why, since Jesus is the son of God and Jesus is 100% of God, and so is the Ghost and so is the Father, the Father is singled out to be called the Father ─ and so on.
