First, the Church doesn’t consider it a sin to be homosexual. It’s not sinful to be tempted by something. Having feelings of same-sex attraction therefore is not in itself wrong. The Church teaches that acting on those feelings is wrong, just as it teaches all sexual activity outside of faithful man-woman marriage is wrong. All of us, gay or straight, are challenged to live chaste lives.
Nor does the Church have a position on how people come to be homosexual. The Catechism of the Catholic Church number 2357 says “[homosexuality’s] psychological genesis remains largely unexplained.”
This happens to be exactly what the American Psychological Association thinks. In the same statement the Governor cites to justify his conversion therapy ban we read:
“There is no consensus among scientists about the exact reasons that an individual develops a heterosexual, bisexual, gay, or lesbian orientation. Although much research has examined the possible genetic, hormonal, developmental, social, and cultural influences on sexual orientation, no findings have emerged that permit scientists to conclude that sexual orientation is determined by any particular factor or factors. Many think that nature and nurture both play complex roles….”
In other words, no one knows how same-sex attraction comes to be. Governor Christie may think he does, but he’s relying on…actually I don’t know what, since science doesn’t back him up. If he just means he doesn’t think anyone chooses homosexual feelings, he’s on the same page with the Church. In number 2358 the Catechism says most people experience same-sex feelings as “a trial” rather than something freely chosen.
Can we leave the Church out of it then, since the Governor’s flat wrong about what it teaches?
