Drawing on European conferences dating back to 1527, Mennonite bishops who had immigrated to present-day Bucks, Montgomery, Chester and Berks Counties endorsed in 1725 a “brotherly agreement” originally drawn up in the Dutch Republic in 1632 and affirmed by Swiss leaders in 1660.
The American Revolutionary War tested the bonds of this fellowship as leaders discussed the proper way to express historic Mennonite convictions against participating in warfare and taking oaths.
In this era, progressive-minded leaders thrust beyond the protective traditional emphasis on accountability to a freer, more congregational, education-oriented, missional and innovative style of conference.
