Such a sleepy title for such an important decision. Let me explain.
Section 4 of the proposed Anglican Covenant is the section that provides a means to discipline Provinces of the Anglican Communion that exercise autonomy to the detriment of the common life of the Communion. The first three sections of the Covenant were approved by the most recent Anglican Consultative Council. Section 4 was strongly resisted by The Episcopal Church and was referred for review and possible revision. This review and possible revision is underway now.
The Church of Ireland is generally considered among the more liberal Provinces of the Anglican Communion and seen as sympathetic to The Episcopal Church. This decision to endorse Section 4 as it stands sends a strong message to the rest of the communion that the Church of Ireland upholds the principle of Interdependance.
