Homosexuality is addressed in Catholic moral theology 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" and "homosexual acts" are viewed as "contrary to the natural law. They close the sexual act to the gift of life. They do not proceed from a genuine affective and sexual complementarity."Nevertheless, gay people must be accepted with "respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided."

The Catholic Church teaches that marriage can be made only between a man and a woman, and opposes introduction of both civil and religious same-sex marriage. Leading figures in the Church have campaigned against same-sex marriage,same-sex civil unions, and other LGBT issues. The Church holds that same-sex unions are an unfavorable environment for children and that the legalization of such unions is harmful to society.


So the question is is the catholic church right?
