All of this "standing" or "kneeling" which receiving the "Lord's Supper" is absolutely ludicrous. If we are to take Jesus' position, He was "inclined" at the table and so were His disciples when communion was taken. The "position" that a person's body takes is irrelavent. It's the condition of the person's heart that matters. He must understand what the Bread and Wine symbolizes, what each represents, and why these elements are used. The Body of Christ's broken body is represented by the "unleavened" bread, and the shed blood of Jesus is represented by the wine. The broken body of Jesus represents what Jesus' Body went through so that we could inheret by grace, through faith immortality, incorruptibility, and physical perfection, and the shed blood of Jesus represents the means to forgiveness of sin for without the shedding of blood, there can be no forgiveness of sin, and the blood of Jesus Christ was the only blood "pure" enough to cleanse us of all unrighteousness.
So talking about kneeling or standing is foolish. It's not the kneeling or the standing that causes us to remember Christ Jesus' sacrifice. We celebrate the communion (eucharist) to remember what Jesus did on our behalf. So talk about this, not about whether one should kneel or stand while remembering the sacrifice that Jesus went through on our behalf. You have just destroyed the very reason for the communion (eucharist), "Do this in remembrance of Me". --Jesus. You can't remember Jesus while arguing about kneeling or standing while receiving the elements of communion (eucharist)
So talking about kneeling or standing is foolish.Well, we have to do one or the other, but to be preoccupied with posture is to miss the point.
I areee with you that the disposition of the heart and mind is of primary importance in celebrating and receiving the Eucharist.
