If the Roman Catholic church would return to Biblical teaching....
You mean like this?
"And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love. No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord." Romans 8:38-39
What did the Pope say? Did he say homosexuality was not a sin? No. He said that God loved the man for who he was. That God's love is unconditional. That's exactly what my Bible teaches. Does your Bible teach that the Pope should have told the man that God hates him?
