Beginning roots

The International Christian Ministries ( ICM ), was established in October, 1981, by its founders U.S. Navy Lieutenant Donald and Missionary Evelyn Duplessis. It was organized as a Christian ministry fellowship, in the home of Reverend Paul Arrington at #3 Duncan Street, on the U. S. Naval Base, Yokusuka, Japan. Organized under the name Full Gospel Christian Cell Fellowship ( FGCCF ) and officially sanctioned by the Commander Fleet Activities Yokosuka Chaplain's Office Command Chaplain to function as a Christian Prayer and Bible study fellowship, the FGCCF conducted weekly Wednesday and Friday meetings in the home of Paul Arrington.



FGCCF quickly expanded in numbers and on December 31, 1981 held the first home Watch Night service where the attendance reached a standing capacity of more than 31 people at #3 Duncan street. Realizing the need to provide more space for the growing fellowship, LT Duplessis opened the now available military base residence at #7 Second Avenue, Yokosuka Base as the second home for weekly meetings. Word had spread concerning this new Christian fellowship and by summer, 1982 the FGCCF expanded its prayer and bible study home meetings to the following military bases: Yokosuka, Atsugi, Kami Seya, Yokohama, Camp Zama, Sagamihara and Sagami Depot. Because of the significant impact and presence of FGCCF on the military bases, LT Duplessis was requested by U S Army Command Chaplain, Camp Zama, Colonel Gordon Prout, to conduct the first Gospel Worship Service, which took place in August, 1982. Word again spread to other military bases concerning Gospel worship services available on the Army base and in 1985, LT Duplessis was supported by military Chaplains on U.S. Naval Air Station Atsugi, U.S. Naval Base Yokosuka and Fleet Activities Base Yokohama to hold Gospel Worship Service programs. Military Gospel services were strengthened by Christian Lay-Leaders who worked together with LT Duplessis and grew in numbers over the next decade. These Gospel services would remain and continue now to be led by succeeding military and civilian Lay-leaders. 


The Next steps

As the 1990's appeared, LT. Duplessis had now returned to Japan as a navy commander and received instructions from the Lord to continue building the ministry once organized as a home fellowship. Commander Duplessis had clearly received divine orders from the Lord to transition the military fellowship to an off-base location in order that more Japanese would be reached with the Gospel message and in 1991, established the first off-base Full Gospel church in Yokosuka City, under the name of Full Gospel Christian Church. A Board of Directors was established and full-scale Christian ministry service programs went forth. The new Church began to draw both Japanese and non-military base worshipers, which included Japanese university students, foreign embassy workers and English teachers.



In 1996, Commander Duplessis, while preparing for military retirement, received a night vision from the Lord which shown him a multitude of people, from many nations, stand with raised hands in Japan. He questioned the Lord for understanding, which led to God's instructions for him to change the name of the ministry to International Christian Ministry


( ICM ) whereby it is know today. Commander Duplessis obeyed and followed the Lord's instructions and officially established the ICM as a United States foreign missions ministry and transitioned into full-time ministry upon retiring from the U. S . military. He changed uniforms from military officer to civilian clergy, and, as an already ordained Christian minister of many years, began a full time ministry work, along with Evelyn, as Missionary Pastors. The vision from the Lord was very clear and God instructed that it be written as such: preach and teach the Word of God ( Bible ), show believers how to receive the promises of God in daily living, find out the callings from God upon individuals and then send them forth into the word to serve the Lord in their calling. Five ministry pillars were given by God in this vision and they were to be always required for worshippers and never removed from the ministry. They are: 1) Prayer, 2) Study, 3) Tithe, 4) Fellowship, and 5) Consecrate.



New Doors

Throughout the remaining decade, under the missionary leadership of Pastor and Missionary Duplessis, ICM would see tremendous change as many foreigners began to worship within its ministry doors. Now operating as an officially registered foreign missions organization, ICM was received into the Japan Evangelical Missionary Association ( JEMA ) where it holds a long-standing JEMA Membership of many years. Outreach into the local Japanese and international community took place and included: Feeding the homeless,  visiting hospitals, prisons and shelters for battered for women and dozens of Christian retreats and evangelism outreach activities.

Fulfilling the Vision

In 2005, upon receiving his ministry appointment as prelate, Bishop Duplessis led  ICM to expand its missionary boarders and church-planting into nations outside Japan in fulfillment of its vision requirements to send forth those with ministry callings ( into the uttermost parts of the world ). Thus, from 2006-2010, ICM mission branches were established in the countries of Cameroon, Ghana, Nigeria and Philippines and pastors were appointed over each branch. A ministry headquarters was officially set up in Japan at the ICM ministry location in Ebina City, Kanagawa.

A ministry book store was established to supply the ICM branches and a ministry Gospel choir program was established as a pre-evangelism outreach program to reach Japanese people. 



Bible School -  ISLA ISOM


In 2010, the ICM officially launched its vision-based missions bible school and partnered with  Good Shepherd Ministries International, in facilitating programs through its International School of Ministry ( ISOM ) under license to educate believers in basic foundations of the bible. The ISOM program, which now outreaches into local Christian communities, throughout Japan now functions as an independent learning institution, established by the name of International- Schools and Learning Academics ( ISLA ). To date, the ISLA ISOM School has held five academic/education recognition and graduate ceremonies and graduated more than 50 students.

The Transition

In 2014, ICM transitioned into a fully Japan registered independent Church ministry and Christian business organization and the entire ministry is governed by an international Board of Directors. 


The ICM has impacted the lives of more than 7,000 worshipers, with hundreds of souls making the decision to receives Jesus Christ as Lord and Savior. More than 250 Christian water baptisms, 80 Child/baby dedications, 35 Christian wedding ceremonies, and  2 Funeral services have been conducted. Dozens of 5-fold ministry, apostolic and evangelical ministry representatives have been sent forth both in Japan and throughout the world, where they serve as Pastors, Missionaries, Teachers, Seminarians, Diaconate, Prelates, Chaplains, Institutional Christian Representatives, Christian ( Artist ) Singers and Musicians. 


Worshiping Nations

The number of worshiping nations throughout the history of ICM has exceeded 37 and the currently active worshipping nations are 11. The ICM continues to positively impact the lives of many worshipers in their spiritual capacity, knowledge capacity and relational capacity with others in  demonstrating the love of God throughout the world.
