You can’t understand Lincoln or the Civil War itself without understanding the religious milieu from which they sprang.
Its sometimes worthwhile to remember that the GOP itself was born when Christians abandoned the Whigs out of frustration with the Whig Party’s unwillingness to take a stand against slavery. When they did so, the Whigs vanished.
And a decade later slavery was done.
Just something for the GOP itself to remember. The day Christians abandon it, it will likewise vanish.
Which may be something that we should do sooner than later.
