A Christian charity organization [World Vison] has reversed its decision to employ Christians in same-sex marriages, after the move prompted a backlash from its major donors and the cancellation of an estimated 2,000 sponsorships meant to help impoverished children around the world.

The charity's current hiring policy requires employees to sign a code-of-conduct contract agreeing not to engage in premarital sex, or to commit adultery if they are married. The charity [. . .] is allowed to have such a hiring policy under U.S. law because it is considered a church.

At one time in the dark ages, I actually went to a church who supported that organization.  Needless to say it was an epoch ago that I quit attending that church, and thus went to one where its charitable arm openly and freely employs GLBT people.
