The fifth song is in Second Samuel, when David spoke to the Lord the words of this song on the day when the Lord delivered him from the hand of all his enemies and from the hand of Saul. He said, The Lord is my rock, and my fortress, and my deliverer; my God will be my protector. If, then, you prove able to examine who are the enemies David defeats and overthrows in First and Second Samuel and how he was made worthy of deserving the Lord’s help and of being delivered from enemies of this kind, then you will be able to sing this fifth song yourself.

Did Jesus come into the world for this purpose, that we [the Jews] should not believe him? To which we immediately answer that he did not come with the object of producing unbelief among the Jews; but knowing beforehand that such would be the result, he foretold it and made use of their unbelief for the calling of the Gentiles. For through their sin salvation came to the Gentiles, respecting whom the Christ who speaks in the prophecies says, A people whom I did not know became subject to me: they were obedient to the hearing of my ear; and, I was found by those who did not seek me; I became manifest to those who did not inquire after me.^[1]

But, as we have said elsewhere on occasion, these heretics refuse to take the blame for what they do to us and they lay the blame on us for what they do to themselves. Who of us would wish them to lose anything, much less that they be lost themselves? If the house of David could win peace in no other way than through the death of Absalom, David’s son, in the war which he was carrying on against his father—although the latter had instructed his followers with great care to keep him safe and sound as far as it was possible for them to do so, that he might repent and receive pardon from his father’s love—what was left for him but to weep over his son’s loss and find comfort for his grief in the peace thus gained for his kingdom? In the same manner, then, our Catholic mother acts when others who are not her sons make war on her—because it is a fact that this little branch in Africa has been broken off from the great tree which embraces the whole world in the spreading of its branches—and although she is in labor with them in charity, that they may return to the root without which they cannot have true life, still, if she rescues so many others by losing some, especially when these fall by self-destruction, not by the fortune of war as Absalom did, she solaces the grief of her maternal heart and heals it by the deliverance of such numbers of people.
