Wilberforce who was responsible for England's giving up the slave trade, argued against slavery on the basis of his Christian principles. John Newton, who had been an officer on a slave ship, gave it up and preached against it when he converted to Christ. The abolitionists in America made their case based on the Bible
And there were Christians using the Bible to justify and support slavery at the same time.
So where is the evidence? Where is a government document that says "We outlaw slavery based on the Bible"?
The US Constitution outlawed slave importation but not based on the Bible.
The Emancipation Proclamation outlawed some slavery under specific conditions but not based on the Bible.
Economics, secular humanism and politics did lead to ending direct slavery but it would take over another 100 years to begin the effort to grant civil rights to African Americans and again, religion, particularly Christianity, supported both sides of the struggle.
Anyone so limited that they can only spell a word one way is severely handicapped!
