I believe the Catholic Church will eventually accept active homosexuality in its members so long as they tend toward monogamy and otherwise follow the teachings of the Church.
the Church is already changing to be more inclusive:
The Pope Francis Statement That Changed the Church on LGBT Issues
Quote:
"If someone is gay and searches for the Lord and has good will, who am I to judge?" -Pope Francis
Quote:
A person once asked me, in a provocative manner, if I approved of homosexuality. I replied with another question: ‘Tell me: when God looks at a gay person, does he endorse the existence of this person with love, or reject and condemn this person?’ We must always consider the person. Here we enter into the mystery of the human being. -Pope Francis
a parallel example: the Hare Krishnas view sex as illicit unless for procreation. yet its founder Srila Prabhupada, in response to a gay devotee saying they had great difficulty being celibate, is
reputed to have said: "Then just find a nice boy, stay with him and practice Krsna consciousness."
in an increasingly liberal world, faith leaders will be more tolerant of deviation on the margins so long as the fundamentals of the religion are maintained. in Christianity a fundamental message is "Jesus died for your sins" not "homosex is Wrong" imo.
