I found the following to be of interest:
When I was getting ready to leave for England to take up a scholarship at
Cambridge, Fr. Menas had already become Patriarch Kyrillos VI. I went to
see him and asked, “Where should I receive Communion?” He said, “If the
Greeks allow you to receive Communion, go.
Here we have a very highly esteemed saint in the Coptic Church permitting a Copt to received Communion from the Eastern Orthodox. To Copts/OOs: do you have any similar quotes from Patriarch Kyrillos VI regarding the Eastern Orthodox. Do you have any quotes from him regarding the Roman Catholics? I have not read or heard of any contemporary EO saints allowing an EO to receive sacraments from an OO or Coptic priest.
