I doubt it was in the form that we have it now; a service of worship, a "communion hymn", special liturgy and everyone walks up to stand, or kneel, at a table to receive a wafer/bit of bread and a sip of wine - that was my point.
Neither Acts 2 nor 1 Corinthians 11 describe that.
He gave instructions all over the place
Where, for example?
Where does God's word say "and when you meet together, make sure that only ordained clergy break bread and say a prayer of blessing over it and the wine"?
No, they don't. They do believe, however, that the congregation calls its ministers into service according to a formal process and that the validity of certain acts,
Yes - they also rightly believe, and teach, that every member ministers and has a ministry.
Even Peter said that we are a holy priesthood, James told us to confess our sins to one another and Paul said that we are all the body of Christ; the head being Jesus, not an Archbishop/Pope.
As followers of Christ, Children of God and those who are filled with the Spirit, we should all be able to break bread, honour the Lord and commemorate his death.
Well, that seems to be a valid Eucharist. You said there was a called and ordained officiant and the proper elements were used (bread, wine).
It was.
I was thinking more of the comment made in this thread that we do it "properly" or not at all. Some might say that wasn't "proper". And to be honest it was so long ago I couldn't swear that even bread and wine were used.
But neither is that what you are trying to convince me of. For an example of that, you'd have had to say that at the end of a long day, a group of unordained Christian men and women passed around the remains of a watermelon, everyone present ate some, and everyone gave their testimony about what God meant to them personally. Something like that.
I'm not actually trying to convince you; I said that my belief is that you don't need ordained clergy present to make Communion "valid" - that is not a Scriptural teaching. I said also it is my belief that eating and drinking, on your own or with friends, and remembering the Lord's death - in his presence - is just as much "Communion" as the service that I described earlier.
What does God think; how does he see it?
Does he refuse to bless people who eat and drink bread and wine without the "correct" person being present?
Are people who take cake and juice/tea and biscuits/bread and water or whatever they have to hand, but do it in sincerity and with thankful hearts actually sinning?
What of people who take the correct elements in a proper service with an ordained minister, but who do it because they are told to/they have always done it/their hearts are far from God or they don't actually have a relationship with him? Are they still better than a devout, sincere Christian who remembers the Lord's death while eating a sandwich and drinking juice?
How is someone in the scenario that you described not in communion with God?
