The Pope Gay Marriage Comments – Catholic Pope Francis Endorses Same-Sex Unions

in a recent interview Catholic Pope Francis endorsed same-sex civil unions. as with most religions, the quote-unquote leaders are pedantic.the rules are ever-evolving, and believers never know what’s currently okay and what’s not.
I’m not sure exactly how Catholicism works, but what does the pope endorsing same-sex civil unions, as opposed to same-sex marriage, mean to the Catholic community?
