Earlier quoted context omitted.
I had a long drive where I listened to The Great Courses, which had a set on early Christianity. I think the professor was from Notre Dame. The early church was wrestling with polytheism (is the OT god seemed really different from the NT god) and it eventually had to get resolved by the Council at Nicaea at Constantine's behest.
I've never heard anyone say the early church wrestled with polytheism. Maybe that's my bias nestled in Christian circles of not using that word, in favour of something more like "the nature of the triune Godhead", etc.
"...what kind of God could outstrip the attractions of all other things? Could any unitary, single-person god do so? Hardly, or at least not for long. Single-person gods must, by definition, have spent eternity in absolute solitude. Before creation, having no other persons with whom they could commune, they must have been entirely alone.
Love for others, then, cannot go very deep in them if they can go for eternity without it. And so, not being essentially loving, such gods are inevitably less than lovely. They may demand our worship, but they cannot win our hearts. They must be served with gritted teeth.
How wonderfully different it is with the triune God. In John 17:24, Jesus speaks of how the Father loved Him even before the creation of the world. That is the triune, living God: a Father, whose very being has eternally been about loving His Son, pouring out the Spirit of love and life on Him. Here is a God who is love, who is so full of life and blessing that for eternity He has been overflowing with it..."
