"It is necessary, therefore, to try to understand the causes for same-sex attraction: there may be difficulties in the relationship with the father, an overly possessive mother, a homosexual experience at an age when one is very impressionable, or sexual abuse. We must help young men and young women to understand better these attractions to their own sex, so that they might be convinced that they are not "born that way". The Lord did not create a "homosexual person", and therefore that cannot be someone's deepest identity."
