Exactly what is "Progressive Faith" anyway?
"Progressive," in that sense of the word, means something that is in favor of social anarchy. And social anarchy provides the socio-political climate for socialism.
That trend has been pushed in the USA for at least about 150 years. People like Henry Beecher and Susan Anthony started it in this country. ...that is, if I didn't miss any earlier proponents of the same while researching.
Liberal churches that interpret the bible to allow abortion, homosexual marriage, and anything else they want.
It's like a bible filled with blank pages. Lots of room to right your own 'truth'. I a more biblical frame of reference it's "white wahed tombs full of dead men's bones".
