The King James Bible renders Matthew 16:18 as Jesus saying: "And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell (Greek hai´des) shall not prevail against it." A modern English translation reads: "Also, I say to you, You are Peter, and on this rock-mass I will build my congregation, and the gates of Ha´des (the common grave of mankind) will not overpower it."(New World Translation)
Jesus did not tell Peter that the "congregation"(Greek ek·kle·si´a) would be built upon him, but that it would have as it's foundation himself as the Christ.(Greek Khri·stos´ ) The apostle Peter, some thirty years later, wrote: "Coming to him as to a living stone (Ps 118:22), rejected, it is true, by men, but chosen, precious, with God, you yourselves also as living stones are being built up a spiritual house for the purpose of a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ." He then quotes from Isaiah 28:16: " For it is contained in Scripture: “Look! I am laying in Zion a stone, chosen, a foundation cornerstone, precious; and no one exercising faith in it will by any means come to disappointment.â€Â(1 Pet 2:4-6)
The apostle Paul wrote, in speaking to the Ephesians, said that “you have been built up upon the foundation of the apostles and prophets, while Christ Jesus himself is the foundation cornerstone.â€Â(Eph 2:20) Thus, Jesus is the "rock-mass" upon which he built his "congregation".
The apostle Peter’s name means “piece of rockâ€Â(Greek pe´tros) whereas “rock-mass†is from the Greek word pe´tra. That the apostles did not understand Jesus’ statement to signify that Peter was the rock-mass is evident from the fact that they later disputed about who seemed to be the greatest among them. (Mr 9:33-35; Lu 22:24-26) There would have been no basis for such disputing had Peter been given the primacy as the rock-mass on which the congregation was to be built. The Scriptures clearly show that as foundation stones, all the apostles are equal. All of them, including Peter, rest upon Christ Jesus as the foundation cornerstone. (Eph 2:19-22; Re 21:2, 9-14)
The “congregation†that Jesus was speaking of is not the “church†as many consider it, with all it's various sects. Rather, Jesus was focused on those who would make up the “kingdom of Godâ€Â, for this was the “congregationâ€Â. The apostle Paul wrote to the Corinthians: “to the congregation of God that is in Corinth, to you who have been sanctified in union with Christ Jesus, called to be holy ones.â€Â(1 Cor 1:2) Paul also wrote to the Corinthians: “For I am the least of the apostles, and I am not fit to be called an apostle, because I persecuted the congregation of God.â€Â(1 Cor 15:9) He further wrote to the Hebrews that “you have approached a Mount Zion and a city of [the] living God, heavenly Jerusalem, and myriads of angels, in general assembly, and the congregation of the firstborn who have been enrolled in the heavens.â€Â(Heb 12:22,23)
This "congregation of the firstborn" is made up of only a small number of individuals chosen by God, for Jesus said: "Have no fear, little flock, because your Father has approved of giving you the kingdom."(Luke 12:32) These are the ones spoken of at Daniel 7:21,22, in which Daniel saw in vision this: "I kept on beholding when that very horn made war upon the holy ones, and it was prevailing against them, until the Ancient of Days came and judgment itself was given in favor of the holy ones of the Supreme One, and the definite time arrived that the holy ones took possession of the kingdom itself."
This "congregation" forms the "kingdom" that Jesus taught all to pray for in the "Lord's Prayer" at Matthew 6:9,10. Jesus, on the night before his death, told his eleven faithful apostles: "I make a covenant with you, just as my Father has made a covenant with me, for a kingdom."(Luke 22:29) This "kingdom" was created by God to restore what Adam lost in the Garden of Eden, life on a Paradise earth in perfect health among those who have genuine love for God and neighbor (Matt 22:37-39) and are called "meek ones".(Ps 37:11,29; Matt 5:5) It is a heavenly government made up of individuals "bought (with Jesusshed blood)...for God out of every tribe and tongue and people and nation, and you made them to be a kingdom and priests to our God, and they are to rule as kings over the earth.â€Â(Rev 5:9,10)
