The Pope had to approve homosexuality because the Catholic Church has allowed too many sins thus far, like pork, adultery, idolatry, and unclothed women. Those things are banned biblically, you're not supposed to eat swine in the bible, have sex outside marriage in the bible, make images or pictures, and the women should cover themselves which is why 90% of idols and paintings of Mary (as) her head is covered. But they allowed all these things in the church by the religious leaders practicing them or not forbidding them among the congregation/people. They allowed sin after sin after sin to the extent that they rendered themselves irrelevant in any moral issue or social debate. Even gays are standing bold in front of them. Why would the public listen to a church who says homosexuality is banned but then allows OTHER sins in society? This is the danger of religious institutions allowing small individual sins, because sins are like an avalanche. Once one layer of snow slides and tumbles down the mountain, other layers of snow will become loose, weaken, and slide down as well, and soon you'll be buried by a mountain of snow from all directions. Islam is the last religion left with the moral high ground to challenge the world's current issues, the Jews and Christians committed moral suicide a long time ago.
