For there are some eunuchs, who were so born from their mother's womb: and there are some eunuchs, who were made eunuchs of men: and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.
All Commentaries on Matthew 19:12 Go To Matthew 19
Jerome
AD 420
There are three kinds of eunuchs, two carnal and the third spiritual. One group are those who are born this way. Another are those who are made into eunuchs by captivity or for pleasuring older women. The third are those who “have made themselves eunuchs for the kingdom of heaven” and who become eunuchs for Christ though they could be whole men. The last group are promised the reward. The other two, for whom chastity is not a matter of willing but necessity, are due nothing at all. We can put it another way. There are eunuchs from birth who are of a rather frigid nature and not inclined to lust. There are others who are made eunuchs by men, those who are made so by philosophers, others who are made weak toward sex from their worship of idols, and still others who by heretical persuasion feign chastity so as to falsely claim the truth of religion. None of the above is receptive to the kingdom of heaven. Only the person who for Christ seeks chastity wholeheartedly and cuts off sexual impurity altogether [is the genuine eunuch]. So he adds, “He who is able to receive this, let him receive it,” so that each of us should look to his own strength as to whether he can carry out the commands of virginity and chastity. Chastity in itself is agreeable and alluring; but one must look to one’s strength so that “he who is able to receive this may receive it.” It is as if the Lord with his words were urging on his soldiers to the reward of chastity with these words: He who is able to receive this let him receive it; he who is able to fight, let him fight and conquer. .
