Like many Western churches, the Church of Scotland has been divided in recent years over the ordination of gay clergy in committed relationships, and, more generally, over the status of homosexuality for Christian ethics. Yet there has been no academic research undertaken which situates the debate within the wider context of Scottish theology. This failure has resulted in theological and ecclesial impasse, which this paper seeks to remedy through a diagnostic analysis of division over homosexuality, drawing upon the analytic tools developed by R. G. Collingwood. While this article has as its focus the Church of Scotland, its method and conclusions will be relevant to other Protestant denominations, especially Reformed churches such as the Presbyterian Church (USA).
