Malcolm Horsnell came to McMaster Divinity College in 1978 after teaching in the School of Continuing Studies and the Near Easter Studies Department at the University of Toronto. Malcolm is an ordained Baptist minister and pastored churches in the Baptist Convention of Ontario and Quebec. Malcolm was a regular faculty member at MacDiv for 25 years. He was also Associate Dean (1994-2003) and Director of Basic Degree Programmes (1998-2003). He retired in 2003 to become Emeritus Professor of Old Testament Interpretation. He still visits MacDiv on a regular basis and has been involved in some adjunct teaching.

Malcolm believes that to be in an institution where learning, teaching, worship and ministry come together is a great blessing. He believes in the development of a Christian worldview, rooted in the Bible and in an understanding of history, a worldview informed by the experience and practice of ministry and which is relevant in the context of contemporary developments in science, philosophy, theology and the social sciences, such as sociology and anthropology.

As well as many journal articles, Malcolm has published A Review and Reference Grammar for Biblical Hebrew (1999). His Magnum Opus has been the University and government funded Mesopotamian History Project funded by the Canadian government and McMaster University, which resulted in three published volumes (1999-2003), volume three (2003) being a CD-ROM of all the research data (over 7200 ancient texts) used in the project. In 1992 Malcolm was instrumental in establishing the McMaster Computer Assisted Theological Studies (McCATS) Centre, housed in the College and greatly used by the MacDiv community.

Over the years Malcolm has taught courses in Old Testament, Old Testament Theology, Apocalyptic, Hebrew Wisdom, Hebrew Poetry and Psalms, the Hebrew language, Biblical Concepts of Aging, Akkadian (the language of ancient Mesopotamia), and the History of Ancient Israel.
