Augustine of Hippo — on Phil 2:7 (ON DIVERSE QUESTIONS 73)

“He did not take on his humanity in the simple way that a person puts on clothes, as something exterior to him. Rather he took on human form in a manner inexpressibly more excellent and more intimate than that. The apostle has made it sufficiently clear what he meant "He was made to appear in human likeness." He was not exhaustively reduced to being a man. He rather assumed the true human estate when he put on the man.”
