Revised Standard Version Catholic Edition

Can he enter a second time into his mother’s womb and be born?” ⁵ Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. ⁶ That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.^[a]
