... In fact, Jesus went on to comment on his own teaching when questioned further: "Not everyone can accept this teaching, 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 others, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let anyone accept this who can." (Matthew 19:11-12)
So what is a eunuch? In Greek, the word is eunochos, and it occurs eight times in the Greek scriptures. The word usually refers to castrated men, but it has many meanings, and one of them is "an ineffectual, powerless, or unmasculine man."
One recalls that Alexander the Great, in fact, had a male lover called Bagaos, who was described as a eunuch.
