Gay Marriage and the Future of Human Sexuality ➙

In effect, if marriage is now understood as a lifelong sexual contract between any two adult human persons with no specification of gender, then the allowance of gay marriage renders allmarriages “gay marriages.” Given such a situation, were it not for the space afforded by canon law (namely, the possibility of church marriage) a resort to cohabitation - which has hitherto been understood as “common-law marriage” - would be the only logical path for clear-thinking Christians.
Wow.
