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.

“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.

All in Revelation, and all about the vision of John in Revelation.
And never during his earthly life. Never in all of his preaching. Yet, during his earthly life, in repeated discourses to the apostles, he enjoined them to baptize, celebrate the Eucharist, and to forgive sins. All functions still carried out in the Catholic Church, and not carried out in other Christian bodies.
