It’s no stretch and it makes logical sense. It’s fundamentally what liberalism is all about - destroying the moral underpinnings of society. Each liberal is a god.
My concern is how many catholics will vote for God? I was stunned when my very active, very religious Greek Orthodox friend recently came out in favor of SSM. We’re really behind the curve on this.
The homosexuals aren't making their stunning social and political inroads by themselves. How could they? They only represent 2 - 3% of the population. They're making these inroads because they have huge numbers of heterosexual allies who agree with the LGBT premise: namely, that wedding and bedding aren't primarily about sacred procreative sexuality, but about adult satisfaction.
Let's face it: if marriage is about celebrating a relationship of mutual satisfaction and love between adults, there's no reason why it would have to be a man and a woman.
I would say your friend is not a very religious Greek Orthodox practitioner if he disagrees with Christ’s teaching on marriage in Matthew 19:4-6.
