Alcuin of York — on Rev 3:12-13 (COMMENTARY ON REVELATION)

“He that shall overcome, I will make him a pillar in the temple of my God. God's temple is the Church, according to this: The temple of God is holy, which you are. [1 Cor. 3:17] Since not only the preachers, but also the good listeners triumph over the old enemy, and in this verse everyone who overcomes is said to become a pillar in God's temple, we are forced to confess that a pillar is the same as the temple, that is the universal Church. In what follows, and he shall go out no more, it is openly shown that the Church, in the younger brother, had once passed from the unity of faith and work it kept in the prophets under the law to the error of perfidy and perverse work; but it was recovered through the killing of the fatted calf. [Luke 15:11-31] Alternatively, all of us, Jews as well as Gentiles, went out in Adam; but after we have been brought in victorious to the second Adam, we are made into a pillar of God's temple, because, overcoming the temptations of the old enemy through the blood of that same Mediator of ours, we are established in the heavenly glory of the saints by that steadfastness in the commandments which we are demonstrated to have lost in the first Adam. But we shall never go out again, because no incitements of the enemy shall tear us away from that common happiness of the heavenly fatherland. Note also that he says he has a God as he speaks according to his humanity. And I will write upon him the name of my God, and the name of the city of my God, the new Jerusalem, which cometh down out of heaven from my God, and my new name. He that hath ears, let him hear what the Spirit saith to the churches. The name of the Father being written on the one who overcomes means that he becomes his Son by adoption of the Spirit. Indeed, with what pen is it written, if not with the grace of the Spirit of both? Whence the apostle: The Spirit himself giveth testimony to our spirit, that we are the sons of God. [Rom. 8:16] As for Jerusalem, it translates to "sight of peace." It is said to come down out of heaven from God because the Church of the elect, which directs its course towards the sight of heavenly peace with the steps of love, went down, as it was predestined to, into the womb of the Virgin together with the Lord, whose body it is; or it is because its number increases every day through heavenly grace. It is called new because, through baptism and love, it is stripped of the oldness of the earthly man and clothed in heavenly newness; whence this: The old things are passed away, and behold all things are made new. [2 Cor. 5:17] So the name of Jerusalem is written on the victor when he joins the number of the saints. As for where we get all this from, it is revealed when it is added and my new name (implying I will write) namely the one that was given in time to the same Mediator, that is "Christ." This is where our dignity and high position comes from, this is the cause of our being called sons of God, New Jerusalem, and Christians. Therefore, where we hear the sum of all salvation, let us at last put a due end to this book.”
