Missouri District UPCI.

The United Pentecostal Church International (UPCI) has been among the fastest growing denominations in North America since it was formed in 1945 by the merger of the Pentecostal Church, Incorporated, and the Pentecostal Assemblies of Jesus Christ. From 617 churches listed in 1946, the UPCI in North America (United States and Canada) today lists 4,358 churches (which includes 4099 autonomous and 258 daughter works), 9,085 ministers, and reports a Sunday School attendance of 646,304. Moreover, it is also located in 175 other nations with 22,881 licensed ministers, 28,351 churches and meeting places, 652 missionaries, and a foreign constituency of over 3 million, making a total worldwide constituency of more than 4,036,945.

The UPCI emerged out of the Pentecostal movement that began in Topeka, Kansas in 1901. It traces its organizational roots to October 1916, when a large group of ministers withdrew from the Assemblies of God over the doctrinal issues of the oneness of God and water baptism in the name of Jesus Christ.
The basic governmental structure of the UPCI is congregational with local churches being autonomous: the congregation elects its pastor and its leaders, owns its property, decides its budget, establishes its membership, and conducts all necessary business. The central organization embraces a modified presbyterian system in that ministers meet in sectional, district, and general conferences to elect officials and to conduct business of the organization.
