Which contemporary bible are you quoting? It sounds like some catholic add ons were added here disguised as quotes from Jesus. I would like a link to this.
It's the New American Bible. Here is the same passage from the King James:
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.If you want, I can also give passages from Paul. While all are not called to celibacy, you cannot deny that it is praised in the Bible.
