In recent years, some evangelicals have argued that questions of sexual ethics should not be considered tests for orthodoxy, and that evangelicals should instead unite over more primary issues of Gospel proclamation. How should evangelical leaders respond? Are questions of sexual ethics secondary issues about which Christians should agree to disagree, or are they non-negotiable aspects of Christian teaching? This presentation will argue for the latter, and that any weakening of Biblical teaching in this area in the name of unity will both sabotage our work of discipleship and radically undermine our witness to the world. It will also suggest practical steps for Christian leaders and organisations as they seek to take a faithful stance in response to questions of sexual ethics.
