Lang Pastoral Charge was formed as a United Church charge in 1925, part of Weyburn Presbytery, with preaching points at Lang, Crocus Plains and Lake View [Lakeview]. In the late 1930s, Crocus Plains moved to Lewvan Pastoral Charge, joining Lewvan and Colfax appointments. Between 1951 and 1958, the charge joined with Milestone to create the joint Lang-Milestone Pastoral Charge. Between 1974 and ca.1986, appointments included Parry, as well as Lang and Milestone.

On January 1, 2013, the joint charge amalgamated with Rouleau-Wilcox Pastoral Charge to create the new Soo Line Pastoral Charge, with preaching points at Rouleau, Lang and Milestone.
