Doctor Anderson's experience as a teacher began as a graduate assistant in the 1960s and includes teaching and administration in four colleges and universities. He has been a student of the Bible for several decades, and has taught Bible classes and courses since the 1970s. In 2012 he published his book, "ROMAMS: Standing in Grace and Truth." He continues to strongly advocate for the unity of the Bible and to oppose Modern Dispensationalism with its antinomianism and unwarranted division of the Scriptures and Covenant Theology's Covenant of Works and hyper-Calvinism.
