The thing about Mennonites is there is no such thing as THE Mennonite church. It’s really the Mennonite churches, with no central authority. Some of the churches are much more liberal and some more traditional. And some of it depends on where in the world they are located.
The Netherlands was a place where great forces were battling to see their view of the world hold sway. The Dutch Reformed Church with its predicant preachers, strict and orthodox, wanted to have the final world over the standards — both legal and social — being set in the new nation. They were opposed by the Remonstrants, their more liberal-minded rivals who were required to meet in private homes instead of public churches. And perhaps most powerful of all was the merchant class, whose vast wealth kept the heart of Amsterdam beating throughout the Dutch Golden Age.
