Irvin Baxter Jr. is an American Oneness Pentecostal minister who is the founder and president of Endtime Ministries, a Christian organization devoted to presenting his views on Christian eschatology. Baxter is also an author, publisher, broadcaster and international prophecy teacher. Before he founded Endtime Ministries, Baxter served as pastor of the Oak Park Church (UPCI) in Richmond, Indiana for approximately 32 years. Endtime ministries was founded in 1991. Irvin Baxter bought the Oak Park Church from 'The Church of God' congregation in 2002, 11 years after the founding of endtime ministries. Prior to 2002 Irvin pastored at the 'United Penticostal Church' (UPC) in the 1200 block of South 8th street in Richmond, Indiana where he first set up endtime ministries out of the Church. Later he purchased a building on the north side of the UPC church building where endtime operated until they out grew that location. Then purchased a building southeast of the UPC. A commercial building, originally occupied by a bank. Upon the purchase of the Oak Park Church building in 2002, the congregation of the 'UPC' moved to Oak Park and shared the building with the 'Church of God' congregation until the previous owners could find a new home to worship. Irvin separated Endtime from the Oak Park congregation and moved to Dallas where he set up as full time radio and tv evangelist.
According to his website, Baxter became intensely interested in Bible prophecy at the age of 19, when a visiting evangelist taught that the four beasts of chapter four in the book of Revelation were Matthew, Mark, Luke, and John. He believed this was incorrect, and in the next thirty days read the book of Revelation nineteen times. His studies led him to devote considerable time to study Pentecostal and Evangelical eschatology.
