Can an Eastern Catholic recieve communion in an Orthodox Church?

My question is this: Can an Eastern Rite Catholic, such as a Marronite, Melkite, etc., who use the same service as Orthodox churches, receive communion in an Orthodox church.
As a member of a Melkite parish, I know the presbyter can give communion to an Orthodox person. I also know that the excommunications were removed by Pope Paul VI and the ecumenical patriarch. I also heard that it was at the Orthodox Priest's discretion. I have received communion in an orthodox church before, but have also been told that I shouldn't! So what's the verdict!

your question presupposes that an all powerful god exists, this is of course a fantasy worthy of the most imaginative child which coincidentally would possess the same level of intellect as your gods creator.

Approach the Orthodox priest and ask permission first. We Catholics (Eastern & Western) and the Orthodox churches use the same reason for saying no: it implies a unity that does not (yet) exist. Yes, the priesthood and sacraments of the Orthodox churches are valid, but their unity with the pope is not. Besides, not all of the Orthodox churches are in communion with each, either. The 6 Oriental Orthodox churches are not in communion with the other 15 or so autonomous/outplayshaloesshes and the Assyrian Church of the East is its own entity...not in communion with anyone...yet! I pray for the day we are all united. So...within Orthodoxy itself, there are distinct groups.

ANSWER:

I can not speak for all of the various ethnic versions of Orthodoxy in America (Greek, OCA, Antiochian, Ukrainian, etc.) but from the Russian Orthodox perspective...
'Holy Communion is a mystery of the Holy Orthodox Faith and is thus only open to Orthodox believers.'

It is not the outward form of the Liturgy (St. John Chrysostom, St. Basil the Great, St. James of Jerusalem, etc.) that makes a person Orthodox, but Orthodox Baptism, Orthodox belief and practice of those belief's that makes someone Orthodox.

When a non-Orthodox person approaches the chalice (at least in the Russian Orthodox Church) that person is assumed to hold the belief's of the Orthodox Faith, a person without this belief and the appropriate preparation (Holy Confession/Repentance) can commune to their condemnation. As we read in 1 Corinthians 11:29-31 there were those that communed unworthily (without due preparation) that became sick or even died.

The priest knowing the seriousness of Communing of the Body and Blood of Christ, can not give it to unbelievers (non-Orthodox) - however well intentioned they may be - lest they be injured through participation in the mysteries.

In a like manner Orthodox Christians may not participate in the mysteries of other Christian (or non-Christian) traditions as it implies a common belief, what the bible calls being of "one mind"; essentially a denial of their Orthodoxy.

I'm sure that you received Orthodox Communion with good in tensions, but I would strongly advise you to not approach the mysteries of the Orthodox Church again until you are a baptized Orthodox Christian.

Only if that church it under the pope can one receive Holy Communion you must ask first to make sure or ask a catholic priest just to make sure.
