Pacifism and abolitionists

When looking at nonviolence, I see how a very good place to start is with pacifists and abolitionists. A lot of the framework for how pacifists and abolitionists begin looking at nonviolence starts with religious framework and rhetoric. Garrison's Declaration of Sentiments seemed to indicate that a lot of early pacifist based their beliefs on christian framework and a lot was based exclusively on the teachings of Jesus. While Garrison did use religion as the foundation for his belief set, it seemed that it was still founded on the belief of a God that bestows judgement upon humanity, thus "vengeance is mine- I will repay sayeth the lord." Do such pacifistic sentiments only apply to humanity? Does Garrison really hope that God bestows punishment? If so, I find it interesting that belief in a judgmental and punishing God relates to Garrison's understanding of what is right and what is wrong. Is judgement and punishment ultimately good, but solely belong to God? I am curious to explore the relationship between religion and pacifism further. When it comes to abolitionists, I find it very interesting how Frederick Douglas seems less motivated by religious reasons than the pacifists. Many of the sentiments that Douglas is expressing seems to stem from "enlightenment" ideals of equality and justice. Though Douglas does make some christian references in his speech, it is more in reference to "man's rights" bestowed by God, thus reinforcing the conceptual foundation in enlightenment thinking. Why is it though, that the foundation for pacifism and abolitionists seem to come from different sources? Is this difference just evident because of the sources chosen, or is there some underlying difference between the foundations of American pacifism and abolitionism? Both philosophies seem to hold very similar ideals, but deep down may be based on very different framework.
