Having shown that the pretexts usually alleged for second marriages have no weight, St. Ambrose declares that he does not condemn them, though from the Apostle’s words he sets forth their inconveniences, though the state of those twice married is approved in the Church, and he takes occasion to advert to those heretics who forbid them. And he says that it is because the strength of different persons varies that chastity is not commanded, but only recommended.
