"9. This Psalm can be taken as in the Person of Christ another way; which is that whole Christ should speak. I mean by whole, with His body, of which He is the Head, according to the Apostle, who says, You are the body of Christ, and the members. 1 Corinthians 12:27 He therefore is the Head of this body; wherefore in another place he says, But doing the truth in love, we may increase in Him in all things, who is the Head, Christ, from whom the whole body is joined together and compacted. Ephesians 4:15-16 In the Prophet then at once, the Church, and her Head (the Church founded amidst the storms of persecution throughout the whole world, which we know already to have come to pass), speaks, O Lord, how are they multiplied that trouble me! Many rise up against me; wishing to exterminate the Christian name. Many say unto my soul, There is no salvation for him in his God. For they would not otherwise hope that they could destroy the Church, branching out so very far and wide, unless they believed that God had no care thereof. But You, O Lord, art my taker; in Christ of course. For into that flesh the Church too has been taken by the Word, who was made flesh, and dwelt in us; John 1:14 for that In heavenly places has He made us to sit together with Him. Ephesians 2:6 When the Head goes before, the other members will follow; for, Who shall separate us from the love of Christ? Romans 8:35 Justly then does the Church say, You are my taker. My glory; for she does not attribute her excellency to herself, seeing that she knows by whose grace and mercy she is what she is. And the lifter up of my head, of Him, namely, who, the First-born from the dead, Colossians 1:18 ascended up into heaven. With my voice have I cried unto the Lord, and He heard me out of His holy mountain. This is the prayer of all the Saints, the odour of sweetness, which ascends up in the sight of the Lord. For now the Church is heard out of this mountain, which is also her head; or, out of that justice of God, by which both His elect are set free, and their persecutors punished. Let the people of God also say, I slept, and took rest; and rose, for the Lord will take me up; that they may be joined, and cleave to their Head. For to this people is it said, Awake you that sleepest, and arise from the dead, and Christ shall lay hold on you. Ephesians 5:14 Since they are taken out of sinners, of whom it is said generally, But they that sleep, sleep in the night. 1 Thessalonians 5:7 Let them say moreover, I will not fear the thousands of people that surround me; of the heathen verily that compass me about to extinguish everywhere, if they could, the Christian name. But how should they be feared, when by the blood of the martyrs in Christ, as by oil, the ardour of love is inflamed? Arise, O Lord, save me, O my God. The body can address this to its own Head. For at His rising the body was saved; who ascended up on high, led captivity captive, gave gifts unto men. For this is said by the Prophet, in the secret purpose of God, until that ripe harvest Matthew 9:37 which is spoken of in the Gospel, whose salvation is in His Resurrection, who vouchsafed to die for us, shed out our Lord to the earth. Since You have smitten all who oppose me without a cause, You have broken the teeth of the sinners. Now while the Church has rule, the enemies of the Christian name are smitten with confusion; and, whether their curses or their chiefs, brought to nought. Believe then, O man, that salvation is of the Lord: and, You, O Lord, may Your blessing be upon Your people. "
