14 But what shall I say, brethren? Let us see plainly what He purchased. For there He bought, where He paid the price. Paid it for how much? If He paid it only for Africa, let us be Donatists, and not be called Donatists, but Christians; since Christ bought only Africa: although even here are other than Donatists. But He has not been silent of what He bought in this transaction. He has made up the account: thanks be to God, He has not tricked us. Need there is for that bride to hear, and then to understand to whom she has vowed her virginity.
There, in that psalm where it says, “They pierced my hands and my feet, they counted all my bones;” wherein the Lord's passion is most openly declared—the psalm which is read every year on the last week, in the hearing of the whole people, at the approach of Christ's passion; and this psalm is read both among them and us—there, I say, note, brethren, what He has bought: let the bill of merchandise be read: hear ye what He bought: “All the ends of the earth shall remember, and turn unto the Lord; and all the kindreds of the nations shall worship in His sight: for the kingdom is His, and He shall rule the nations.”
Behold what it is He has bought! Behold! “For God, the King of all the earth,” is your Bridegroom. Why, then, would you have one so rich reduced to rags? Acknowledge Him: He bought the whole; yet you say, “You have a part of it here.” Oh, would that you were well-pleasing to your Spouse; would that you who speaks were not defiled, and, what is worse, defiled in heart, not in body! You love a man instead of Christ; love one that says, “'Tis I that baptize;” not hearing the friend of the Bridegroom when he says, “This is He that baptizes;” not hearing him when he says, “He that has the bride is the Bridegroom.” I have not the bride, said he; but what am I? “But the friend of the Bridegroom, who stands and hears Him, rejoices greatly, because of the Bridegroom's voice.”
