Alcuin of York — on Rev 1:4-5 (QUESTIONS AND ANSWERS MANUAL ON REVELATION)

“QUESTION: What does it mean that John salutes only seven churches whereas the Master of truth says, Go ye into the whole world, and preach to every creature? [Mark 16:15] ANSWER: Through these seven churches, he writes to the whole Church. Indeed totality is often represented by the number seven, because all this worldly time flies by in cycles of seven days. THERE FOLLOWS: Grace be unto you and peace from him that is, and that was, and that is to come, and from the seven spirits. ANSWER: He wishes the pious people grace and peace from God the eternal Father, the sevenfold Spirit, and Jesus Christ, who gave testimony to the Father in the human form he assumed. He names the Son in the third place as he is going to say more about him. He also names him last because he is the first and the last, and he has already named him together with the Father when he said that is to come. The first begotten of the dead, and the prince of the kings of the earth.”
