Can primates enforce edict?

[Anglican Journal] 2 April 2007--Can the primates’ meeting, which was created in 1978 to provide leaders of Anglican provinces with an opportunity for “leisurely thought, prayer and deep consultation” enforce penalties and offer recommendations to individual and independent provinces that sound more like edicts?

This was a question raised by some Canadian Anglicans and Episcopalians in the United States in reaction to a communiqué issued by primates, or senior bishops, who met in Tanzania Feb. 15-19; the statement set an ultimatum for the American church to ban the blessing of same-sex unions and the consecration of gay bishops.
