Karl Anthony Archer was born in Kingston, Jamaica. He later moved to Carey Park, Duncans, Trelawny, where he attended the Duncan’s All Age School and the William Knibb Memorial High School. In pursuit of becoming an Electrical Engineer, he enrolled in the College of Arts Science and Technology (CAST), now the University of Technology (UTECH), where he pursued a diploma in Electrical Engineering.

While studying at CAST, the devout Baptist Christian was introduced to the Third Angel's Message through "The Carter Report,"an evangelistic series held at the National Stadium in 1986, conducted by world renowned evangelist, Pastor John Carter.  While he didn’t attend the meetings, the message came to his attention through the medium of other students who attended, and who were quarreling on the campus about the messages presented by the evangelist. Karl received a copy of the book The National Sunday Law around the same time.He read it, studied the book of Revelation, and on February 19, 1987, was baptized at the Seventh-day Adventist Church in Duncans. This of course was the beginning of a unique expedition-his call to the gospel ministry.

A year later, Pastor Archer began his studies at West Indies College, now Northern Caribbean University, where he graduated in 1992 with a Bachelor of Arts Degree in Theology. In 2006, he completed a Master of Arts degree in Pastoral Ministry – Leadership and Human Resource Management, at the Trinity Theological Seminary. He went on to complete his Doctor of Divinity degree with the Inter-american Theological Seminary, Northern Caribbean University site, where he graduated in August, 2017.

Karl Archer was first employed by West Jamaica Conference on February 1, 1993, and five years later he was ordained.  He served as pastor to the following districts in West Jamaica: Westgreen, Champers Pen, Falmouth and Lucea. In 2002 he was called to North Jamaica Mission and served as the Stewardship, Youth Ministries Director, and later the Sabbath School, Personal Ministries and Community Services Director.  He also served as district pastor of the Ocho Rios, Exchange, St. Ann’s Bay and Brown’s Town districts. 

On March 26, 2009, at the West Indies Union Conference Executive Committee, Pastor Archer was appointed as Secretary of North Jamaica Mission.  His unique expedition continued, as, at the first quadrennial session of North Jamaica Mission held January 9 and 10, 2010, he was elected to serve as the first President of the North Jamaica Conference. He, along with the officers and directors, were installed on January 10.
