Andrew N. Dugger (1886-1975) was the most famous Church of God, Seventh Day, leader in the twentieth century. He was born in Bassett, Nebraska.

Andrew N. Dugger’s father, A.F. Dugger, Sr., had been an Advent Christian Minister. When commissioned by his church to do a study refuting the Sabbath, A.F. Dugger instead became convinced that the Sabbath should be observed. The result was a book he later published, called The Bible Sabbath Defended. For more than thirty-five years until his death in 1910, A.F. Dugger, Sr., was a leader in the Church of God, Seventh Day. His son Andrew, a school teacher and farmer, was in his early 20’s when his father died.

A bright light in the sky around him seemed to Dugger to be a sign from God that he should follow his father’s footsteps in the ministry. A.N. Dugger immediately sold his large farm and equipment, and went to the University of Chicago, where he majored in theology and public speaking, mastering Greek, Hebrew, and German.

Dugger periodically returned to Bassett to visit his mother and Effie Carpenter (1895-1980), a student of his whom he wanted to marry. Although he first proposed to her when she was sixteen, it wasn’t until 1925 until they were married. They shared fifty years together.

Soon after college graduation, Dugger was invited by the Executive Committee of the Church of God to move to Stanberry, Missouri, to become editor of The Bible Advocate, a position his father had held before being forced to retire because of ill health. In 1914, Dugger arrived in Stanberry to begin his work in the ministry. For eighteen years he was editor, also serving as President of the General Conference. As field representative, he traveled widely, holding evangelistic meetings and public debates. The famous "Porter Dugger Debate," between Dugger and W. Curtis Porter, a Church of Christ minister, was later published as a book of over 230 pages. In 1919, Dugger wrote The Bible Home Instructor, which publicized the Seventh Day Church of God, and substantially increased its membership during the 1920s.

Two of Dugger’s most adamant doctrinal positions were: a scriptural form of church organization with leaders chosen by lot rather than election, and a world headquarters in Jerusalem, Israel. After visiting Israel for only a year in 1931-32, Dugger returned to live in Sweet Home, Oregon. In 1936, A.N. Dugger and C.O. Dodd published A History of the True Church, which traces Sabbath-keepers from apostolic times to modern days. Dugger greatly influenced Herbert Armstrong, who was for years affiliated with the Church of God, Seventh Day, but later formed his own church, the Radio (later Worldwide) Church of God.

Dugger remained pastor at Marion, Oregon until 1953, when he and Effie settled permanently in Jerusalem, and launched the Mt. Zion Reporter. His aggressive leadership resulted in thousands of converts around the world. Andrew N. Dugger died in 1975 at the age of 89. Dugger’s son-in-law, Gordon Fauth, continued the Jerusalem work at Mount Zion Reporter, P.O. Box 568, Jersualem, Israel.
