The synoptic gospels agree with Paul’s testimony. I can quite understand other Christian churches reading Jesus’ words more as “do this in commemmoration of me” rather than the Catholic mystery of bread and wine turning into the actual flesh and blood of Jesus. I have been led by Jesus to celebrate communion in other churches: the first time I cried and said “Lord, this is a PROTESTANT church” and the Lord asked, “are you afraid of me, Ian?” Blessedly it was a High Church of England, which believes in transsubstantiation, so I had no problem. Other times I KNOW they do not believe in transsubstantiation but simply join in with them in commemmoration of our Lord Jesus. Although the Pentecostal practice of passing round broken crackers and thimbles of blackcurrant juice is pushing it a bit!
Having said that, partaking of the body and blood of my Lord became a wondrous event since I was Born Again. I constantly tell my Protestant Born Again friends they are missing out!
One Maundy Thursday we happened to be on holiday in India, where I was born. We went to my mother church and the Indian Monsignor’s sermon claimed that the Last Supper celebrated two momentous church institutions: one, the introduction of the Eucharist, the other the institution of the priesthood, because only priests could celebrate communion. Now THAT is an interpretation too far! Priests were instituted by God to serve and keep themselves scrupulously holy in the desert temple and later the temple in Jerusalem. God WAS present behind the veil in the Holy of Holies and only the High Priest went behind that veil on Yom Kippur. And he had to have kept himself ritually pure or else he’d be zapped: which is why he wore bells on the hem of his garment: if the bells stopped, the No. 2 I/C had to gird his loins and drag him out. And God help him if he skipped a ritual!
But at the instant of Jesus’ death on the cross, the veil of the temple was rent in two. God was no longer present in the temple. As He promised in prophecy he would live in the hearts of his people, who no longer had to make severe pilgrimages to worship God in a building cos He was right there making his abode with them. One can conclude that special ultra-holy people are no longer required to serve God. How much more staggeringly wonderful is the thought that God, Jesus and the Holy Spirit LIVE right there IN you! But baby Christians and those of weak faith or even no faith do need experienced Elders to chair meetings and guide their flock. Among Paul’s list of God’s appointments (1 Cor 13:28) are those with gifts of administration. Which includes me out cos I was a hopeless manager who just could not delegate!
