From Bishop Wedgwood, on the Eucharist

“Why do we celebrate the Holy Eucharist? We do so because Our Lord himself said to His apostles and their successors: “Do this in remembrance of Me”. We can picture how the disciples were sad and perplexed as on the eve of His passion He told them of His impending departure. And we can see him breaking the Bread and blessing the Cup as He told them He was bequeathing to them a rite which should keep His presence perpetually among them and help them to maintain that unity and sense of fellowship which they had found in their common devotion to Him. 'As oft as men shall do these things,' He said – if we may slightly paraphrase the utterance - 'they shall do them in remembrance of Me.' How wonderful the gift that He has left to us, only to those who know and day after day seek Him in the silence and peace of their hearts. How exquisite the thought that by His incorporation in ourselves and the merging of our consciousness into Him, we grow more and more like unto Him Who is our Sun of Righteousness, the very life and nectar of our being. ….. He is with us upon a thousand altars daily and the whole world is blessed by His Presence.”
