Louis DeBoer was born in the Netherlands on June 29,1944. He was baptized in the Gereformeerde Kerk in which his father was an elder. At age 5 his family emigrated to Ontario, Canada. He grew up in Clarkson, Ontario, Canada as a member of the Christian Reformed Church. He attended the University of Toronto and graduated with a degree in Mechanical Engineering in 1967.

By this time he was seriously concerned about the doctrinal decline in the Christian Reformed Church and especially the radical actions and teachings of such organizations as the AACS, CJL Foundation, and CLAC etc. operating in the Christian Reformed community. His concerns led him into close friendship with Rev. John Byker of the Second Christian Reformed Church of Toronto and one of the founding pastors of the Orthodox Christian Reformed Church. When the moderator of Classis (Presbytery) Toronto made a public speech defending homosexuality and maintaining that the scriptures permit homosexual acts in love between consenting adults he publicly confronted him. As a result of these actions Rev. Byker was suspended from the ministry of the Christian Reformed Church for pressing charges against the moderator for his views on homosexuality. This led Mr. DeBoer to leave the Christian Reformed Church and join a local fundamentalist church.

Prior to that Mr. DeBoer had resigned his position as a Service Engineer with a large international manufacturer of compressors to answer a call to teach at a Christian High School in the Toronto area. This position he too felt compelled to resign because the school harbored several radical teachers associated with the AACS who advocated use of illegal drugs, promoted the Black Panthers, and declared that the United States needed a revolution to establish social justice etc.  Mr. DeBoer went to New England to visit friends and came under the tutelage of Rev. Ennio Cugini.  As a result of his influence, instruction, and direction he answered a call to preach in a small mission church in Northern Maine. This he did for a year and a half under the sponsorship of the Clayville Church of Foster,  Rhode Island, while also working a fulltime secular job. During that time he met and married his wife, the former Faith Lamoureux, a member of the Clayville Church, where her father served as an elder. They have been blessed with four children; Louis Elijah (May,1973), Rachael Evangeline (December, 1974), Vincent Gabriel (May 1977), and Renee Serena (September 1980). 

Due to lack of sufficient support and with growing family responsibilities (He was serving as a pastor without any salary) Mr. DeBoer relocated to New Jersey and joined the Bible Presbyterian Church where he served as head of the mathematics and science department at Faith Christian High School. There he soon identified with the more Reformed element for he had not forsaken his Calvinist heritage even while sojourning among Fundamentalist Baptists. He continued to study and prepare for the ministry and to serve as pulpit supply in Bible Presbyterian churches.  During this time he founded a theological newsletter entitled, "The Pilgrim" that he edited for two years. Early in 1974 he received an independent ordination into the gospel ministry. While he continued to teach in the High School he was called to pastor the Bible Presbyterian Church of Berlin, New Jersey. When a majority of the faculty at Faith Christian High School resigned in 1974 over lack of standards and discipline he was among those who preferred to leave rather than work ineffectually in a way contrary to one’s principles. This compelled him to return to secular work. In the1976 schism in the Bible Presbyterian Church he sided with the group that was being expelled and became the first Moderator of the American Presbyterian Church at its inception.

In the late 1970’s he founded the American Presbyterian Press and published his first book, "The New Phariseeism" a refutation of the cult of British-Israelism. He subsequently published "The Hebrew Republic" by E. C. Wines, an exposition of Biblical principles of government as found in the laws of Moses, and two books on baptism, "Letters on Baptism" by E. Fairfield, and "Immersion and Immersionists" by MacKay. He also published Charles Hodge’s, "A Constitutional History of the Presbyterian Church in the USA", and Thomas M’Crie’s, "The Life of Melville".  Recently he has published his second book entitled, "The Divine Covenants", his third book "Lord of the Conscience", a defense of religious liberty, and his fourth book "The Fruit of the Vine", a Biblical defense of temperance.   His latest book is Hymns, Heretics, and History a critical history of hymnody.  

In God’s providence Rev. DeBoer resigned his secular position for reasons of health in 1997. He has been working exclusively as Editor of the American Presbyterian Press and in writing a number of theological works, in laboring at many projects for his Presbytery, and in doing contract work for other Christian organizations. He has resided in Rhode Island since 1990.
