聖子
For centuries, the Christological perspective on son of man has been a natural counterpart to that of son of God and in many cases affirms the humanity of Jesus just as son of God affirms his divinity. In the 5th century, Saint Augustine viewed the duality of son of God and son of man in terms of the dual nature of Christ in hypostatic union, in that the son of God became the son of man through the act of incarnation and wrote: "Since he is the only Son of God by nature, he became also the Son of Man that he might be full of grace as well."
