And he said unto him,
Verily, verily, I say unto you, Hereafter you shall see heaven opened, and the angels of God ascending and descending upon the Son of man.
All Commentaries on John 1:51 Go To John 1
Cyril of Alexandria
AD 444
Common now to all is the word which seals the faith of Nathanael. But in saying that angels shall be seen speeding up and down upon the Son of Man, that is, ministering and serving His commands, for the salvation of such as shall believe, He says that then especially shall He be revealed as being by Nature Son of God. For it is not one another that the rational powers serve but surely God. And this does not take away subjection among the angels (for this will not be reasonably called bondage). But we have heard of the Holy Evangelists, that angels came to our Saviour Christ, and ministered unto Him.
