"The holy man, persuaded that they belonged to some idolatrous people and that in their own language they gave adherence to the Christian faith, invited them to receive baptism. "I think," said he to them, "that you bathe often, for all the hollows of the rocks are full of pure water, and as I came to your assembly I saw several of you plunging into these natural baths. Now purity of body is the image of spiritual purity." And he taught them the origin, the nature, and the effects of baptism. "Baptism," said he to them, "is Adoption, New Birth, Regeneration, Illumination." And he explained each of these points to them in succession. Then, having previously blessed the water that fell from the cascades and recited the exorcisms, he baptized those whom he had just taught, pouring on each of their heads a drop of pure water and pronouncing the sacred words. And thus for three days and three nights he baptized the birds."
