The Church of Nigeria's canon law revision of 14 September 2005 redefined the terms of inter-provincial Anglican unity from a focus on communion with the Archbishop of Canterbury to communion based explicitly upon the authority of scripture and historic doctrinal statements. This paper will examine the revision as an ecclesiastical reform connected to, yet independent from, the current controversy over human sexuality. Pertinent issues of episcope and ecclesial communion as they are affected by the canon law change will then be examined. Finally, the ecumenical implications of the revision will be discussed, with particular reference to the Anglican–Roman Catholic dialogue and the ‘continuing’ churches of North America.
