You don’t need Greek metaphysics to understand the divinity of Christ, but you do need Greek metaphysics to comprehend three in one and one in three.
The Gospel of John says nothing about what is meant in the Creed by three in one and one in three.
You are correct. I commend you for making an excellent point. However, we both agree that the Gospel of John makes clear the divinity of Christ. Arianism and other faiths that reject the divinity of Christ are heretical. That includes Mormonism.
I sure don't!
COMPREHENDING ONE God that has TWO physical bodies: now THAT takes some doing!!
