I was a white american convert to the Eastern Orthodox Church and I would close my lips around the spoon. In my parish we were taught to “just take It,” rather than waiting for the priest to try dumping the Eucharist from the spoon into your mouth. I think that many people feel that one might catch a sickness from the Eucharist. The priests finish off the Chalice after everyone communes and they don’t get sick. Of course if you partake unworthily, that is another story…I was surprised to see people closing their lips around the spoon in a video some time back. So I asked about it and got the response that this is not unusual someplaces, now I don’t remember where. Perhaps outside the US since here we always talk about opening your mouth wide like a baby bird for the priest or deacon to toss the Eucharist in with the spoon, in the Churches where this is the practice.
