One of the chief problems of Biblicism is that it fails to make the vital distinction between the Bible and Christianity. Christian faith is a living tree rooted in the soil of Scripture. We cannot remove the tree from the soil in which it is rooted and expect it to survive; but neither are we to think that the tree and the soil are the same thing! They are not. Put simply, the Bible and Christianity are not synonymous. Yes, they are connected, but they remain distinct. Scripture is the soil; Christian faith is the living tree. They are connected, but they are not the same thing. So if the Bible assumes that slavery is both a tolerable and inevitable institution (see Ephesians 6:5), even explicitly stating that slaves are slaveowners’ property (see Exodus 21:21), that doesn’t mean this is the Christian ethical position on slavery. Christianity is not a slave to the Bible— Christianity is a slave to Christ! Out of the soil of Scripture grows a mature Christian faith that is not only able, but required to oppose all forms of slavery in the name of Jesus. Rooted in the soil of Scripture, Christianity is capable of growing an ethical branch of justice called abolition.
