In 1897 Isaiah Rosenberger was ordained as a minister and a helper to Joseph Nahrgang in the Blenheim congregation near New Dundee, Ontario. He served as assistant and then as pastor of that congregation until 1908 when the family moved to the recently established pioneer Mennonite community at Cressman near Guernsey, Saskatchewan. At Guernsey he served as an assistant to Bishop Eli S. Hallman and as pastor of the congregation from 1912 until 1919 when Hallman was in the United States. His workload eased when Hallman returned in 1919 and Moses H. Schmitt, a minister ordained in the West Zion Mennonite Church near Carstairs, moved to Guernsey.
Rosenberger was one of the pioneers of the Quill Lakes Mennonite reserve near Guernsey. He faithfully served the Sharon Mennonite Church there, and the Alberta-Saskatchewan Mennonite Conference with which the Sharon church was affiliated, until he returned to Ontario in 1936. There he renewed his fellowship with the Blenheim congregation where he remained until death. His fellowship and service with that congregation were greatly appreciated during the time of his residence there.
