Should the Episcopal Church be practicing 'open Communion?

[Episcopal Life Online] 5 Sep 2007--There is a movement afoot in the Episcopal Church to invite everyone present at the Eucharist, baptized or unbaptized, to receive Communion. This invitation, issued usually by the presider stating something like, "This is Christ's table, and all are welcome," defies the Constitution and Canons of the church and the ordination vows of the one presiding. The rationale given is that since Jesus welcomed all, we should not put up restrictions, that this is an important means of showing the radical hospitality of Jesus.
