One of the key Scriptural sources for the theology of celibacy is Matthew 19:12:
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. He who is able to receive this, let him receive it. (RSV)
Most Christian thinking about celibacy has focused on the clause about eunuchs for the sake of the kingdom of heaven. Within both the Catholic and Orthodox traditions, a celibate vocation is understood as a choice to give up marriage for the sake of service to God.
Because Christians who think about celibacy at all focus almost exclusively on voluntary celibacy, many gay and lesbian people object to the prohibition on gay sex in the Christian tradition on the grounds that it imposes involuntary celibacy on people who are exclusively attracted to their own sex.
But this stems, at least in part, from focusing on only a third of what Jesus has to say here. In this post, I want to think a little bit about the relevance of the other two clauses: those who were born eunuchs and those who were made eunuchs by men.
