Please forgive an outsider butting in again. I note several instances of posters saying “the communion line is not the place for denying communion”. I would have to disagree. As a seminarian, I am blessed to serve in many parishes. I have witnessed many times in many parishes the priest or deacon turning someone away from communion. Always with utmost charity. If a priest is not familiar with the communicant he will inquire as to the parish they belong, last confession, and have you completed the fasting and prayer rule. If he is not satisfied with the answer the communicant is blessed and turned away with the request to meet after liturgy. A priest is responsible to defend the Eucharist and must answer to God for any instance it was administered improperly or irreverently. I have never seen someone react poorly. Mayb bcause this is a know thing with Russians? When traveling I am sure to call the parish I will be visiting ahead of time so that they know to expect me. Some priests even require attandence at vespers the evening before the liturgy followed by confession with the priest who will be communing you the next morning.
Perhaps this is because Orthodox parishes are typically much smaller and it is only proper for a priest or deacon to distribute the gifts that makes it a bit different for us. When I visit Catholic Churches I am astounded that just about everyone receives. It is almost as if they are more stigmatized to remain in the pew and admit that they are an unworthy/unprepared sinner (we all are) than to recieve improperly.
Thanks for listening to an outsider, please know that my statements are not meant to cause offense but only to share how a sister church deals with these issues.
Spraznikom! Joyous feast! Have a blessed Dormition/Assumption.
