Revelation 1: 1: The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:
John represents the Bride of Christ in the Book of Revelation.
The angel that showed John such revelations described represents Brother Branham (Malachi 4: 5: Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD:).
The Book of Revelation proves that the angel which showed John many things was indeed a Gentile prophet.
Revelation 21: 17: And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.
John said that the angel was a man, thus it was a man measuring the wall of the City.
Revelation 19: 10: And I fell at his feet to worship him. And he said unto me, See thou do it not: I am thy fellowservant, and of thy brethren that have the testimony of Jesus: worship God: for the testimony of Jesus is the spirit of prophecy.
The man revealing things to John was a Gentile because the testimony of Jesus after it was rejected by the Jews was then given to the Gentiles (Acts 13: 46: Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you the Jews: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles.).
Revelation 22: 8 - 9: And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things. Then saith he unto me, See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God.
The angel refused worship from John, saying that he was a fellowservant and of the prophets, therefore this angel was a Gentile prophet.
