Jesus saw Nathanael coming to him, and said of him,
Behold an Israelite indeed, in whom is no guile!
All Commentaries on John 1:47 Go To John 1
Cyril of Alexandria
AD 444
Not having yet used proof by means of signs, Christ endeavoured in another way to persuade both His own disciples, and the wiser of those that came to Him, that He was by Nature Son and God, but for the salvation of all was come in human Form. What then was the mode that led to faith? God-befitting knowledge. For knowledge of all things befitteth God Alone. He receiveth therefore Nathanael, not hurrying him by flatteries to this state, but by those things whereof he was conscious, giving him a pledge, that he knoweth the hearts, as God.
