What religious group was the first to formally oppose slavery in America in 1688?

The Mennonites were the first religious group to formally oppose slavery in America in 1688. This significant opposition was articulated in a petition presented at a Quaker meeting in Pennsylvania, which highlighted the immorality of slavery and called for its end. The Mennonites, part of the Anabaptist tradition, emphasized the principles of peace, nonviolence, and the belief in the equality of all individuals, which led them to condemn the practice of slavery early in American history. This action marked an important moment in the development of abolitionist thought in the United States and showcased the ethical stance that guided their community.

In contrast, other groups mentioned, such as the Pilgrims, Shakers, and Methodists, had different priorities and timelines regarding their views on slavery. While various religious groups would eventually address and take stances against slavery, the Mennonites distinctively took this formal stance as early as 1688, setting a precedent for other groups that followed.
