Wrong.
Jesus commands to write
Revelation 1:9-11 I, John, your brother and partner in the tribulation and the kingdom and the patient endurance that are in Jesus, was on the island called Patmos on account of the word of God and the testimony of Jesus. I was in the Spirit on the Lord's day, and I heard behind me a loud voice like a trumpet saying,
“Write what you see in a book and send it to the seven churches, to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea.”
Revelation 1:17-19 When I saw him, I fell at his feet as though dead. But he laid his right hand on me, saying,
“Fear not, I am the first and the last, and the living one. I died, and behold I am alive forevermore, and I have the keys of Death and Hades. Write therefore the things that you have seen, those that are and those that are to take place after this.
Revelation 2:1 “To the angel of the church in Ephesus write:
Revelation 2:8 “And to the angel of the church in Smyrna write:
Revelation 2:12 “And to the angel of the church in Pergamum write:
Revelation 2:18 “And to the angel of the church in Thyatira write:
Revelation 3:1 “And to the angel of the church in Sardis write:
Revelation 3:7 “And to the angel of the church in Philadelphia write:
Revelation 3:14 “And to the angel of the church in Laodicea write:
WRONG!
Revelations is NOT among the 4 Gospels and the words of Christ.
Here we have John writing as the Angel instructed him regarding things to come.
NONE of these are the Gospels Christ instructed His disciples to preach to all nations.
The latest belief is that the John that wrote Revelation was not one of the 12. He was John of Patmos.
