158. Instruction Concerning Celibacy. Mt. 19:10–12

His disciples said to him: “If such is the obligation of a man toward his wife, it is better not to marry.” But he said to them: “Not all can accept this saying, but only those to whom it is given. For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the Kingdom of Heaven.”

Let the one who is able to accept this accept it.
