The crisis has arisen from more than one direction; one major cause has been that no discipline has been exercised within the Anglican communion (led by the Archbishop of Canterbury) on the Church of Canada and the Episcopal Church USA for their allowance of practising homosexual clergy. This has prompted the withdrawal of some evangelicals and their realignment with the Province of South Cone (which covers six South American countries), whose Primate, Archbishop Gregory Venables, remains in communion with Canterbury. By this means, the disaffected — of whom Dr. Jim Packer is the best known — support their claim to remain Anglican.
