Question: What Christian groups belonging to the church communities of Anabaptist denominations named after Menno Simons, did a Canadian novelist and short story writer write of?
Context: Adam Pastor was born Roelof Martens or Martin, at Dörpen, Westphalia, and was a Catholic priest at Aschendorf till 1533 when he joined the peaceful wing of the Anabaptists.  At the Anabaptist conference in Goch in 1547, at which Menno Simons was chairman, Pastor was censured for his anti-Trinitarian views, and then in Lübeck in 1552 he and Simons held a debate on the deity of Christ and the Trinity. The Mennonites are Christian groups belonging to the church communities of Anabaptist denominations named after Menno Simons (1496–1561) of Friesland (which today is a province of the Netherlands).  Through his writings, Simons articulated and formalized the teachings of earlier Swiss founders.  The early teachings of the Mennonites were founded on the belief in both the mission and ministry of Jesus, which the original Anabaptist followers held to with great conviction despite persecution by the various Roman Catholic and Protestant states.  Rather than fight, the majority of these followers survived by fleeing to neighboring states where ruling families were tolerant of their radical belief in believer's baptism.  Over the years, Mennonites have become known as one of the historic peace churches because of their commitment to pacifism. Menno Simons College is a Mennonite college in Winnipeg, Manitoba, Canada.
