Moosomin Pastoral Charge was formed as a new United Church charge in 1925, containing preaching points at Moosomin (Bethel United Church) and Orangeville, which was soon after reassigned to Wapella Pastoral Charge. Additional points included: Fleming (until closure, January 1, 1985).

Prior to Union, there had been Methodist and Presbyterian congregations in the area. The churches amalgamated in 1925, in what had been previously the Moosomin Methodist Church (built in 1889, dedicated 1890), and the Presbyterian St. Andrew's Church building (dedicated 1903, located on the site of an earlier Presbyterian Church, built 1884) was sold soon after.
