Who organized boycotts of churches that endorsed slavery?

Christian views on slavery are varied regionally, historically and spiritually. Slavery in various forms has been a part of the social environment for much of Christianity's history, spanning well over eighteen centuries. In the early years of Christianity, slavery was an established feature of the economy and society in the Roman Empire, and this persisted in different forms and with regional differences well into the Middle Ages.[1] Saint Augustine described slavery as being against God's intention and resulting from sin.[2] In the eighteenth century the abolition movement took shape among Christian people across the globe.

In the eighteenth and nineteenth century debates concerning abolition, passages in the Bible were used by both pro-slavery advocates and abolitionists to support their respective views.

In modern times, various Christian organizations reject the permissibility of slavery.[3][4][5][6]
