I have to take this with a grain of salt since it came from the NYT. But let’s say, for the sake of argument, it’s true.
From what I read, he only supported the idea of civil unions for gay couples as a “lesser of the two evils”, comparable to Benedict saying that a male prostitute using a condom to prevent spreading an STD is a “lesser of two evils”.
Either way, it is not true that Francis is waiting for an opportunity to change doctrine or allow same-sex unions. A lesser evil is still evil, and Francis knows that. He never said that sodomy is okay.
Bottom line, both sides of the ideological spectrum are looking to nab Francis for something. In other news, the sky is blue and bears dump in the woods.
