Glossa Ordinaria
Catena Aurea · Johannesevangelium 3
He that cometh from above is above all: he that is of the earth is earthly, and speaketh of the earth: he that cometh from heaven is above all. And what he hath seen and heard, that he testifieth; He that is of the earth is of the earth; i. e. is earthly, and speaketh of the earth, speaketh earthly things.
That is, from the Father. He is above all in two ways; first, in respect of His humanity, which was that of man before he sinned: secondly, in respect of the loftiness of the Father, to whom He is equal.
