A few years ago we were instructed by one of our bishops to chant the communion hymn one time, then read the 10th pre-communion prayer, and then continue chanting the communion hymn as needed. (Previously we just chanted the communion hymn after reading the prayer.)
If you celebrated the vesperal divine liturgy, would you read the apolytikion of the feast at thanksgiving prayers?
It seems strange to have the first time hearing the festal apolytikion be when it is read at thanksgiving prayers, but on the other hand, you just did vespers of the feast, and if you had celebrated the complete vespers without the liturgy, you would have chanted the apolytikion of the feast.
