- "The water flowed around the altar, and the trench was filled with the water." [I Kings 18:35]
- "The desert and the parched land will exult; the steppe will rejoice and bloom. They will bloom with abundant flowers, and rejoice with joyful song. The glory of Lebanon will be given to them, the splendor of Carmel and Sharon; They will see the glory of the LORD, the splendor of our God." [Isaiah 35:1-2]
"I find that not only do the Gospels, written after the Crucifixion, proclaim the grace of Baptism, but, even before the Incarnation of our Lord, the ancient Scripture everywhere prefigured the likeness of our regeneration; not clearly manifesting its form, but fore-showing, in dark sayings, the love of God to man. And as the Lamb was proclaimed by anticipation, and the Cross was foretold by anticipation, so, too, was Baptism shown forth by action and by word. Let us recall its types to those who love good thoughts—for the festival season of necessity demands their recollection. . . .
"Again, that marvellous sacrifice of the old Tishbite [I Kings 18] that passes all human understanding, what else does it do but prefigure in action the Faith in the Father, the Son, and the Holy Ghost, and redemption? For when all the people of the Hebrews had trodden underfoot the religion of their fathers, and fallen into the error of polytheism, and their king Ahab was deluded by idolatry, with Jezebel, of ill-omened name, as the wicked partner of his life, and the vile prompter of his impiety, the prophet, filled with the grace of the Spirit, coming to a meeting with Ahab, withstood the priests of Baal in a marvellous and wondrous contest in the sight of the king and all the people; and by proposing to them the task of sacrificing the bullock without fire, he displayed them in a ridiculous and wretched plight, vainly praying and crying aloud to gods that were not. At last, himself invoking his own and the true God, he accomplished the test proposed with further exaggerations and additions. For he did not simply by prayer bring down the fire from heaven upon the wood when it was dry, but exhorted and enjoined the attendants to bring abundance of water. And when he had thrice poured out the barrels upon the cleft wood, he kindled at his prayer the fire from out of the water, that by the contrariety of the elements, so concurring in friendly cooperation, he might show with superabundant force the power of his own God. Now herein, by that wondrous sacrifice, Elijah clearly proclaimed to us the sacramental rite of Baptism that should afterwards be instituted. For the fire was kindled by water thrice poured upon it, so that it is clearly shown that where the mystic water is, there is the kindling, warm, and fiery Spirit, that burns up the ungodly, and illuminates the faithful. . . .
"And “the excellency of Carmel” [Isaiah 35:2] is given to the soul that bears the likeness to the desert, that is, the grace bestowed through the Spirit. For since Elijah dwelt in Carmel, and the mountain became famous and renowned by the virtue of him who dwelt there, and since moreover John the Baptist, illustrious in the spirit of Elijah, sanctified the Jordan, therefore the prophet foretold that “the excellency of Carmel” should be given to the river."
St. Gregory of Nyssa, from A Sermon from the Day of Lights (Epiphany)
