Leask Pastoral Charge was formed as a United Church charge in 1925, part of Prince Albert Presbytery and consisting of Leask, The Reserve, and Kilwinning. As of 1932, the re-named Blaine Lake and Leask Pastoral Charge (just Blaine Lake Pastoral Charge by 1936) included Craigmore, Mt. Olive and Carleton Union points. By 1958, the name had returned to Leask Pastoral Charge and by 1962, it had become Leask - Shell Lake Pastoral Charge, with Blaine Lake, Craigmore and Mildred appointments.

Around 1965, the charge returned to the name Leask Pastoral Charge, with points at Blaine Lake and Craigmore. The point at Shell Lake moved to Spiritwood Pastoral Charge. By 1972, Leask joined the Shellbrook and Craigmore points to form Shellbrook-Leask Pastoral Charge.

Shell Lake Pastoral Charge was formed sometime between 1926 and 1932, part of Prince Albert Presbytery and consisting of preaching points at Shell Lake, Avebury and Hawkeye. Around 1936, Mildred was also moved from Spiritwood Pastoral Charge and added to the charge, alongside Camp Lake and Paddling Lake, while Avebury moved to Rothermere Pastoral Charge (Battleford Presbytery). By the mid-1950s, the charge was not listed in Prince Albert Presbytery.

Spiritwood Pastoral Charge was created between 1926 and 1932, part of Prince Albert Presbytery and consisting of preaching points at Spiritwood, Bapaume and Mildred. By 1936, the Mildred point had moved to Shell Lake Pastoral Charge. Around 1940, the charge appears to have been dissolved, with Spiritwood joining Rothermere Pastoral Charge, in Battleford Presbytery.

Around 1965, the Spiritwood Pastoral Charge re-emerged, part of Prince Albert Presbytery and consisting of Spiritwood, Shell Lake, Twin Bay, Ranger, and Chitek Lake. By 1969, Shell Lake and Spiritwood were the only remaining points. As of 1984, the charge consisted of Chitek Lake (Summer), Glaslyn (Bissell Memorial), Shell Lake (Grace) and Spiritwood (Bissell Memorial). On June 30, 2002, Bissel Memorial Church, in Spiritwood, was re-named Trinity Bissell Memorial United Church. The charge was officially re-named Partners in Faith (Shared Ministry), on June 17, 2014.
