I’ll go you one better, can any democrat be a good “CHRISTIAN?” I for one say, no.
“Liberal Christian” is an oxymoron.
It requires total rejection of the divine inspiration and authority of the Bible and of Jesus direct teachings therein.
No part of liberal ideology is biblically supported. Every part of it is biblically refuted.
And, when confronted with this fact, a “liberal” will reject the bible in favor of their worldly-wisdom based ideology.
James 4:4
You adulterous people, don’t you know that friendship with the world is hatred toward God? Anyone who chooses to be a friend of the world becomes an enemy of God.
