Develop, Equip, Resource, and Empower
Men and Women in Five-fold Christian Ministry

Welcome to MMFI

Founded in 1996 by Bishop Rick Callahan and Dr. Phyllis Callahan, Maranatha Ministerial Fellowship, International MMFI, is an apostolic network of ministers, churches, and missions reaching America and around the world. Led by the Callahans and the Apostolic Board, MMFI exists to develop, equip, resource, and empower men and women of God in five-fold ministry. We, as members, desire to compliment and enhance others' ministries while providing moral and ethical accountability through biblical relationships. We believe that "relationships house the harvest," so we "do life" together while advancing His Kingdom work in every region and nation. So, get to know us and see if MMFI is a connection place for you and your ministry.

Together Serving Him,
Bishop Callahan and The Apostolic Board

Kingdom Alignment &
Ministerial Integrity

September 27-29, 2018

(We've changed the schedule this year to Thursday - Saturday. Please note!!)

Alignment. Integrity. In the daily news, these foundational absolutes have become relative and subjective. However, as God's ministers representing and demonstrating His Kingdom in every area of life, they are our indispensable DNA. Be equipped, challenged, encouraged, and activated at this year's MMFI Leadership Conference! Take in and apply powerful messages and impartation from our founder Bishop Rick Callahan. Receive keen insights from the MMFI Board and leaders. Glean from our Keynote Speaker Mark Pfeifer (see bio below). Updates from our International Directors, anointed worship, and life-giving fellowship will fill the conference. This is going to be good, so REGISTER TODAY!


mark pfeifer - Keynote Speaker


Mark Pfeifer was born into a family ministry, and represents the fourth generation of ministers from the Pfeifer family. Mark began traveling full-time in 1981, and in 1983, he began to pursue his education and to fulfill the evangelistic call upon his life. After 8 years evangelizing, Mark and his wife Nicki birthed a ministry in Chillicothe, Ohio. In 1991, they started Open Door Ministries, a local congregation with a greater vision for their region, state, and the nations of the world. Through the years, Mark and Nicki have worked to fulfill their ministry vision by expanding their leadership to include several churches in the United States and abroad. Mark oversees SOMA, a network of non-denominational churches. He and Nicki have three children, Andrew (and wife, Lyndsie), Alexandra Pfeifer Eldridge (and husband, Bryce), Austin, and one granddaughter, Edyn Nicole Pfeifer.
