I am an evangelical Christian holding to the Reformed understanding of the faith, but for some 25 years I was a Christadelphian. This is a relatively small, non-mainstream denomination with a number of distinctive doctrines, including a refutation of the Trinity and substitutionary atonement. I studied and achieved a Master of Divinity through the Australian College of Theology and have taught at a local Bible College. My interests are theology (especially Christology and soteriology) New Testament studies and church history. I’m currently preparing a book for publication. It has the working title: “The Trinity Hurdle; Engaging Christadelphians, Arians and Unitarians with the Gospel of the Triune God.” It is a scriptural and historical defence of the doctrines of the Trinity and substitutionary atonement, specifically directed toward Christadelphians but also very relevant for other non-Trinitarian groups such as the Jehovah’s Witnesses (modern day Arians). The objective of this project is to “speak the truth in love” (Eph 4:15) to those who find the doctrine of the Trinity a stumbling block to engaging with mainstream, biblical, Christian faith.
