After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said,
Come up here, and I will show you things which must be hereafter.
All Commentaries on Revelation 4:1 Go To Revelation 4
Victorinus of Pettau
AD 303
Since the door is shown to be opened, it is manifest that previously it had been closed to men. And it was sufficiently and fully laid open when Christ ascended with His body to the Father into heaven. Moreover, the first voice which he had heard when he says that it spoke with him, without contradiction condemns those who say that one spoke in the prophets, another in the Gospel; since it is rather He Himself who comes, that is the same who spoke in the prophets. For John was of the circumcision, and all that people which had heard the announcement of the Old Testament was edified with his word.
