The United Pentecostal Church International (UPCI) has been among the fastest growing church organizations since it was formed in 1945 by the merger of the Pentecostal Church Incorporated and the Pentecostal Assemblies of Jesus Christ. From 521 churches in 1945, the UPCI in the United States and Canada grew to 4,459 churches (including daughter works and preaching points) and 9,413 ministers in 2013. In the same year it reported works in 201 nations outside the U.S. and Canada with 34,491 churches and preaching points; 21,485 licensed ministers; 886 missionaries; and a constituency of 2.4 million. The international fellowship consists of national organizations that are united as the Global Council of the UPCI, which is chaired by the general superintendent of the UPCI. Total constituency is estimated at 3 million.

The governmental structure of the UPCI is basically congregational in that local churches are self-governing: the congregation elects its pastor and other leaders, owns its property, decides its budget, establishes its membership, and conducts all necessary business.

The general 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. The highest governing body of the UPCI is the General Conference, and between conferences it is governed by the Board of General Presbyters (General Board). Its chief officers are a general superintendent, a general secretary-treasurer, and two assistant general superintendents. World Evangelism Center is the UPCI headquarters building located in Hazelwood, Missouri, a suburb of St. Louis.

The Texas District UPCI is one of three Texas districts within the state. The Texas District UPCI operates primarily in the Northeast Texas region. The Texas District office is located in Lufkin, TX, on a beautiful sixty-acre campground including offices and conference center. It is also home to the Texas Bible College.
