That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Ver. 6. That which is born of the flesh, &c.] Whole man is in evil, and whole evil in man. Quintilian saw not this, and therefore said, that it is more marvel that one man sinneth than that all men should live honestly; sin is so much against man's nature. Many also of the most dangerous opinions of Popery (as justification by works, state of perfection, merit, supererogation, &c.) spring from hence; that they have slight conceits of concupiscence, as a condition of nature. Yet some of them (as Michael Bains, professor at Lovain, &c.) are sound in this point.
