It's still the same white Southern church that is Republican today but was Democrat 50 years ago. The same white Southern church that never particularly wanted to regard blacks as "brothers in Christ" and never had any problems with Jim Crow or lynching.
Blacks have not forgotten or forgiven this and therefore refuse to subordinate their churches to the political agenda of the white Southern church.
Thank you for adding this perspective. Since I never lived in the South, I had not thought of this. You're probably right. It is a challenge for any group of people (or individuals, including me) to change their perspectives when the circumstances change.
And for the past 50 years the black Baptist churches/Pentecostal churches have abandoned expository Bible teaching which builds character to ride political hobby horses. Look at the trade-off, far more illegitimacy, poverty, and crime than before the Civil Rights movement.
Before you ask, the white Christian church should not be entertaining political causes either. Any church that invites a politician to speak to the congregation is a whore.
So what then? So they support evolution, abortion, and homosexuality? Is that how they express their independence from the white church?
Abort enough of your children, Bishop Patterson! That'll show whitey!
