One of the biggest deceptions that non-affirming churches have gotten away with is this notion that the church has always been non-affirming. They'll say things like, "We believe in the historical or traditional view of marriage—one man, one woman."
However, non-affirming churches and denominations keep having this funny problem—their creeds, confessions, or books of order say nothing like that. Therefore, those churches will have a big meeting, vote on "traditional marriage" language, and then add that to their confessions and official beliefs.
Without one bit of irony! They are literally editing their beliefs documents to be more homophobic.
