There is also a third testimony, as the Apostle teaches us: “For all our fathers were under the cloud, and all passed through the sea, and were all baptized to Moses in the cloud and in the sea.” And further, Moses himself says in his song: “Thou sentest Thy Spirit, and the sea covered them.” You observe that even then holy baptism was prefigured in that passage of the Hebrews, wherein the Egyptian perished, the Hebrew escaped. For what else are we daily taught in this sacrament but that guilt is swallowed up and error done away, but that virtue and innocence remain unharmed?
