According to the Catechism of the Catholic Church, “homosexual acts are intrinsically disordered” and “under no circumstances can they be approved.”
“The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided,” it says.
“These persons are called to fulfill God’s will in their lives and, if they are Christians, to unite to the sacrifice of the Lord’s Cross the difficulties they may encounter from their condition. Homosexual persons are called to chastity. By the virtues of self-mastery that teach them inner freedom, at times by the support of disinterested friendship, by prayer and sacramental grace, they can and should gradually and resolutely approach Christian perfection.”
In 2021 the Vatican’s doctrinal office issued a clarification approved by Pope Francis that the Church cannot bless same-sex unions because “God cannot bless sin.”
The Vatican also stated at the time that “the Christian community and its Pastors are called to welcome with respect and sensitivity persons with homosexual inclinations and will know how to find the most appropriate ways, consistent with Church teaching, to proclaim to them the Gospel in its fullness.”
In his response to the question about laws that criminalize homosexuality, Pope Francis also described the ending of the pop opera “The Prodigal Son” as an example of how “God is generous in his mercy.”
“If we preached more about that and not about nonsense, we would be better off,” the pope said.
