I notice that the Churches are beginning to address the issue of online communion. On the whole they are saying it cannot be done which is not surprising as it is a way of being church that is beyond their immediate control and it even challenges the need for the institutional church.
I have been producing podcasts of services of holy communion for a few years. Personally, although I am fully aware of what they mean to me, I claim nothing as far as my listeners are concerned. They are what they are. But should the liturgists et al of the churches need to put online communion into a properly labelled box I suggest that they only need to ask themselves one question which is:
"Who changes the bread and the wine into the body and blood of Jesus Christ - the priest, the people or God?"
Once they have sussed that out the efficacy of internet eucharists should become apparent - even to the most complexity craving theologian.
