This removal of baptism as a prerequisite to communion echoes a practice that is already (non-canonically) widespread in some parts of the Episcopal Church and is common practice in some other denominations. The theology behind it is that in the name of inclusivity, we should extend open table fellowship to all, regardless of baptismal status. Without getting too much into the theology here, I wish to raise an issue that does not seem to be addressed widely, namely the ecumenical implications of such a change.
