Rev G. I. Williamson was born in Des Moines, Iowa, USA in 1925. He was a professional musician during the years immediately prior to, during, and after the Second World War in which he served in the 184th Army Ground Forces Band. He was married during the war to his wife, Doris, in 1944 while serving in the Army, and is the father of three daughters (grandfather of eleven and great-grandfather of seven). Soon after he was released from military service he was converted under the ministry of the late W.W. Orr, then pastor of Westminster United Presbyterian Church in Des Moines, where he felt the call to the ministry. He graduated from Drake University in 1949 and received the Bachelor of Divinity Degree from Pittsburgh-Xenia Theological Seminary in 1952. After being ordained, and serving for a short time in the old United Presbyterian Church of North America, he went on to serve in the Associate Reformed Presbyterian Church, the Orthodox Presbyterian Church and the Reformed Presbyterian Church of North America. However, most of his ministerial service has been in the Reformed Churches of New Zealand, and the Orthodox Presbyterian Church. He is semi-retired at present, but still serves as a member of the Orthodox Presbyterian Church's Committee on Christian Education and its Committee on Ecumenicity and Interchurch Relations. He also preaches and teaches frequently in United Reformed Churches of North America in Northwest Iowa, USA. He is author of several books of which The Westminster Confession of Faith (for Study Classes), The Westminster Shorter Catechism (for Study Classes) and The Heidelberg Catechism (a Study Guide) are the most widely known. He currently edits a journal for elders and deacons of the Orthodox Presbyterian Church called Ordained Servant. Other writings of Rev. Williamson are available on the web at:
