Twenty-one years ago, Scott Anderson had a choice. He could continue to serve as a Presbyterian minister but hide his identity as a gay man. Or he could leave the ministry and live, as he says, "with a sense of integrity" about who he is.

Anderson left the ministry in 1990, believing that door would never open to him again. Now it has.

On Saturday, Anderson, of Madison, will become the first openly gay minister ordained by the Presbyterian Church U.S.A. since the denomination amended its constitution this year to allow it.
