The hypostatic union of two natures. 100% God, 100% man, inseparable and without mixture (not more than man or less than God).Jesus since His incarnation has two natures. He is now both truly and fully a man and was always also truly and fully God, being always the Son of God being one Person distinct from the Person of the Father and Person of the Holy Spirit. They were always the one LORD God.
My argument was saying that Jesus has a human and a divine nature. That is not correct. That is why we use God/man.
The Word actually became flesh. He did not add flesh but became flesh (inseparable).
@SavedByGrace jumped the gun and attacked with the "heresy" charge without taking the time to check out what I was saying.
Jesus has one nature, which a union of two natures (hypostatic union), without mixture and inseparable. This means Jesus does not decide which nature to use today and which to use tomorrow.
