If the Pope did suddenly say that homosexuality or homosexual acts are no longer a sin, would that make it so in the Catholic religion?

No.

(Note: if you want to talk to a leftist, "heterodox" catholic -- possibly some Dhim relative or in-law, you will need a bit more than that, though)

I thought, according to Catholics, the authority to bind on earth was given to Peter and consequently down the line to future Popes?
