Moreover, if anyone has not been baptized, let him be converted all the more securely by receiving the remission of his sins, [so that baptism] as a kind of fire may consume his sins, because Christ baptizes in fire and spirit. Hence, you read of this type in the books of Kings, where Elijah placed wood upon the altar and told them to pour water on it from urns. “And he said, ‘Do the same the second time.’ And they did it the second time. And he said, ‘Do the same also the third time,’ ” and when the water dripped about, Elijah prayed, and fire descended from heaven.
