The Anglican Communion Institute has issued a statement, Announcement Concerning the Anglican Communion Institute via Stand Firm and titusonenine which can be read in full here, or alternatively here, and which concludes:
…In consequence of the legal and ecclesiastical struggles Grace Church and Fr Armstrong are now engaged with, we judge it proper to dissolve our relationship with the web-site and all activities of Grace Church (CANA or TEC), so that the charges of the Presentment and other matters of public trust and ecclesial jurisdiction might be resolved without interference.
We will continue to work on matters related to the Anglican Communion in the same way as previously.
Christopher Seitz, President
Philip Turner, Vice-President
Ephraim Radner, Senior Fellow
Understandably, this statement has not yet appeared on the ACI website operated on behalf of the ACI from Colorado Springs. There are some further comments of interest on titusonenine.
