Many times, people not familiar with Orthodoxy will wonder why bread is available after Liturgy.Sometimes, people mistakenly refer to this as"communion." It is not. In the Orthodox Church,communion is only distributed to the faithful at the appointed time during the Liturgy. It is never given to someone for delayed consumption.The custom of eating some prosphora and drinking some wine mixed with warm water right after taking communion is called "the zapivka" in the Russian Church.
"Zapivka" simply means "washing" or "rinsing," which in this case refers to washing down any remaining particles of the Eucharist.The zapivka is only for those who have taken communion. Those who have not, are given antidoron(blessed bread, not communion) at the end of the Liturgy when they come up to kiss the Cross. This is purposefully called "antidoron," which means literally "instead of the gifts," because it was originally only given to those who did not receive communion at this time, so that they could at least have some prosphora as a blessing, though in current practice even those who did receive communion also receive a piece of prosphora at this time.
