I was raised a Catholic, and I have been very disappointed with Christian views toward homosexuality.
Homosexuality is treated in Roman Catholic Church teaching under two forms: homosexual orientation is considered an "objective disorder" because Catholicism views it as being "ordered toward an intrinsic moral evil", but not sinful unless acted upon. Homosexual sexual activity, by contrast, is viewed as a "moral disorder".
Which comes directly from official Catholic sources (emphasis my own):
Although the particular inclination of the homosexual person is not a sin, it is a more or less strong tendency ordered toward an intrinsic moral evil; and thus the inclination itself must be seen as an objective disorder. [...] Therefore special concern and pastoral attention should be directed toward those who have this condition, lest they be led to believe that the living out of this orientation in homosexual activity is a morally acceptable option. It is not.
I believe that being gay is not a choice, it's a chemical imbalance in the human body that causes one to be sexually attracted to the same gender. And that sexual attraction is, biologically speaking, the catalyst through which a romantic relationship is initiated between two people. That romantic relationship is what leads to the trust and intimate compassion that we define as love between a married couple.
Here's an excerpt from a paper by the American Academy of Pediatrics:
Sexual orientation probably is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences.2 In recent decades, biologically based theories have been favored by experts.
Of course, homosexuals are free to leave the Church, but these teachings cause social issues for millions of these people who have friends and family who are Catholic. Why should homosexuals feel guilty for having intimate romance with those whom they intimately love, while we straight people enjoy that pleasure of life freely? As a Catholic, this didn't makes sense to me, and it seems to be hurting people, so as a straight man, raised Catholic, I feel responsible to ask this question.
How does the Catholic Church justify the belief that homosexuals should not enjoy consensual romantic relationships with the same sexual freedoms that straight people have?
