Luke 22:16-18, 17:20-21 says “For I say unto you, I will not any more eat thereof, until it be fulfilled in the kingdom of God. And he took the cup, and gave thanks, and said, Take this, and divide it among yourselves: For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God shall come…And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.”
Jesus says he will not eat nor drink of the Eucharist (Communion) until the kingdom comes, but in Luke 17 he says the kingdom does not come with observation because the kingdom of God is within in you. The kingdom did not come with observation, but it came with a sound! The kingdom was planted in the heart of the church on the day of Pentecost with a sound. Christ would not be present at the table until the manifestation of the kingdom appeared. The celebration of the Eucharist was to show his death TILL HE COMES! The kingdom then is the coming of the Spirit, but Christ parousia (second coming) happens after his heavenly millennial reign. Christ is with us in the Eucharist. Not only is he with us, he is in the Eucharist. Not only is he in the Eucharist, he is the Eucharist. You are in the kingdom, because the kingdom is in you. We celebrate the kingdom Eucharist of Christ!
