But there is doubt.
The Last Supper
But surely the apostles received Communion in the hand at the last supper? It is usually presumed that this was so. Even if it were, though, we would point out that the apostles were themselves priests, or even, bishops.
But we must not forget a traditional practice of middle-eastern hospitality, which was practiced in Jesus’ time and which is still the case:
one feeds one’s guests with one’s own hand, placing a symbolic morsel in the mouth of the guest. And we have scriptural evidence of this as well: our Lord dipped a morsel of bread into some wine, and gave it to Judas. Did he place this wet morsel into Judas’s hand? That would be rather messy. Did he not perhaps extend to the one whom he addressed later in the garden as “Friend” the gesture of hospitality spoken of above? And if so, why not with Holy Communion, “giving himself by his own hand.”
