Back in March, Pope Francis sparked a wave of headlines when he hinted at the possibility of ordaining married men as priests. Since there’s no evidence that church practice will actually change, reactions to Francis’ comments were premature. But the speculators ignored one interesting point: Opening the priesthood to married men would probably reduce the high percentage of priests who are gay.

While doing research for my book The Sex Effect, I came across many scholars who suggested that preventing priests from marrying altered the makeup of the priesthood over time, unintentionally providing a shelter for some devout gay men to hide their sexual orientation. By continuing to disqualify women and married men, the priesthood attracts men who desire to forgo sex for the rest of their lives in an attempt to get closer to God. Because the church denounces all gay sex, some devout gay men pursue the celibate priesthood as a self-incentive to avoid sex with men, which can help them circumvent perceived damnation.

Of course, many factors influence a person’s decision to join the clergy; it’s not like sexuality alone determines vocations. But it’s dishonest to dismiss sexuality’s influence given that we know there is a disproportionate number of gay priests, despite the church’s hostility toward LGBTQ identity. As a gay priest told Frontline in a February 2014 episode, “I cannot understand this schizophrenic attitude of the hierarchy against gays when a lot of priests are gay.”
