Jerome
Catena Aurea · Matthäusevangelium 19
His disciples say unto him, If the case of the man be so with his wife, it is not good to marry. But he said unto them, All men cannot receive this saying, save they to whom it is given. For there are some eunuchs, which were so born from their mother’s womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven’s sake. He that is able to receive it, let him receive it.
But let none think, that wherein He adds, save they to whom it is given, that either fate or fortune is implied, as though they were virgins only whom chance has led to such a fortune. For that is given to those who have sought it of God, who have longed for it, who have striven that they might obtain it.
