ICOMB is affiliated with Mennonite Brethren mission, historical agencies, publishing, periodicals, and other Anabaptist organizations. Most ICOMB national members are also members of the Mennonite World Conference, our larger global umbrella.

Multiply (previously MB Mission) vision is for holistic church planting that transforms communities among the least reached. ICOMB is the product of the mission effort of Multiply. After a group of church plants becomes an association and achieves a level of maturity, they join ICOMB. Until then, they remain a project of Multiply.
