Well, their classification as “Anabaptists” tells you about their view on infant baptism, no?
I already mentioned the NT/OT views, WRT the Mennonites, and River hit on the CoB’s and Amish.
The local Mennonite churches have become very diversified in rule and worship style, but they all put an extremely strong emphasis on serving others, even more so than other Protestant or Catholic churches. One thing I also noted was that giving/tithing was much stronger there than at any other church I’ve ever attended, it would be normal for them to collect $40k to $100k in a single Sunday morning service, a large fraction of which was put into sponsorship or scholarships, both locally and abroad. Their services did usually contain a sermon, but it was not treated as the pinnacle of the service, the way it would be in most Protestant churches. About 90% of members, maybe more, stay after the usual service for either Bible study or other small groups exercises, and then perhaps half that group stays even after those classes for either a group meal, working in the church garden, or other volunteer work. Very much in keeping with time involved with the church being a several-hours event each Sunday.
Their view on Genesis and creation, at least as expressed by the head pastor of the Mennonite church which I attended, is that it’s more a fable than a history. They focus on only one phrase, “and it was good,” that phrase being repeated numerous times in the first chapter(s).
My mention previously about outward shows of pride are exhibited partly by the family which occupied my house 1775-1922 burned all photographs, documents, and any other possessions of the deceased, which might contain documentation of possessions. So, while numerous old photographs exist of most of the houses in my area, it has been pretty well flushed-out that none exist of mine, despite it being one of the larger and older homes and owned by one of the families most involved in church leadership. The same is true for the house of the father of the man who had built mine. The only answer I could get on that from the local librarian was, ”well, they were a very pious family.” The local historian repeated almost the same phrase, as he had been on the hunt for these photos in publishing some of his own books on the area.
One of the hot topics, causing some disagreement between the local churches when I was attending, was their stance on LGB (now LGBTQ…. etc.). Their doctrine has always been acceptance of all, but some of the civil church leadership in some congregations wanted to go beyond that, and make an affirmation or addition to their bylaws specifically naming the church’s acceptance of LGB’s as members, civil leaders, and even pastors. It was quite a thing to see elderly Mennonites in their traditional conservative dress debate this issue with young Gen.X members. All are remarkably accepting, but they had different views on how far they should go in naming them and identifying them as a special group.
