Whilst there are two births, then, he understood only one. One is of the earth, the other of heaven; one of the flesh, the other of the Spirit; one of mortality, the other of eternity; one of male and female, the other of God and the Church. But these two are each single; there can be no repeating the one or the other. Rightly did Nicodemus understand the birth of the flesh; so understand thou also the birth of the Spirit, as Nicodemus understood the birth of the flesh. What did Nicodemus understand? “Can a man enter a second time into his mother’s womb, and be born?” Thus, whosoever shall tell thee to be spiritually born a second time, answer in the words of Nicodemus, “Can a man enter a second time into his mother’s womb, and be born?” I am already born of Adam, Adam cannot beget me a second time. I am already born of Christ, Christ cannot beget me again. As there is no repeating from the womb, so neither from baptism.
