Here's an article I found on FB that was recently posted:
A small excerpt:
1.
Homosexuality is a behavior, not a feeling or orientation. Therefore, one is not a "homosexual" until one chooses, according to free will, to do something that is contrary to human nature and that is in disharmony with the Way that leads to the healing and perfection of the human person. Of course, a person can commit a sin in the mind by willing to act before the full action is carried out, but sexual temptation, whether opposite-sex or same-sex, is not sin when the tempting thought is dismissed and rejected. Therefore, a "homosexual" is not one who feels same-sex attraction, but one commits a sexual sin with a person of the same sex. This is similarly true for adultery. An "adulterer" is one who commits adultery, not one who feels attracted to those other than his or her spouse if he or she dismisses the temptation and remains steadfastly faithful to the spouse. No matter what form of temptation, whether opposite-sex or same-sex, one may face, we are called to treat our bodies as holy temples and only express the beautiful gift of sexual expression within the context of marriage, a union between a man and woman. So, we are all called to chastity - celibacy outside of marriage and fidelity within marriage, whatever our place in life.
In our secular society, "homosexuality" has been redefined, not as a behavior contrary to good spiritual, mental, and physical health, but as an "orientation" central to a person's identity.
