We are promised a new heaven and a new earth, which the Lord God will make. If new ones are to be created, the old ones will therefore pass away. As for what follows, “Not one iota, not a dot, shall be lost from the law until all is accomplished,” this literally shows that even what is considered least important in the law is full of spiritual sacraments, and it is all summed up in the gospel.

—Jerome, Commentary on Matthew, 1.5.18
