Christ Taught All The Apostles The Same Righteousness!
Did Jesus Christ spend 3-1/2 years teaching Peter, Andrew, James, John, Philip, Bartholomew, Thomas, Matthew, James, Thaddaeus, Simon and Matthais the beautiful concepts and principles of the New Covenant and turn right around a few years later and teach Paul a different righteousness?
As Jesus began teaching His original disciples the concepts and principles of the New Covenant (Matt. 5: 1-16), He suddenly stopped and interrupted His line of teaching to assure those disciples that He had not come to destroy God's spiritual law nor do away with any of the writings of the prophets (Matt. 5: 17-19). Christ reinforced that the basis for the New Covenant was His spiritual law and the prophets by stating that nothing would pass from the law and prophets until all was completed (v. 18).
But did Christ teach Paul that the law was the basis of the New Covenant? Notice, Hebrews 8:10-12, "For this is the COVENANT that I will make with the house of Israel after those days, saith the Lord; I will put MY LAWS into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people." Christ revealed and inspired the recording that those same spiritual laws, which Israel couldn't keep, would ultimately be written in our hearts and minds under the New Covenant.
Notice further what Jesus Christ taught His original apostles. It is found in John 4:21-26. Jesus began teaching those who became the 12 apostles, through His conversation with a woman, that the time would come (day of Pentecost in Acts 2) when they nor any New Covenant Christian would ever have to go up to Jerusalem and be involved in temple worship, tithing to the Levitical priesthood, offering sacrifices, etc., any more. God the Father was seeking under the New Covenant, those people who would worship Him in spirit and in truth. Jesus warned the apostles (Lk. 21:5-6) of the imminent destruction of the temple, so that He could insure the spreading of His message worldwide and not be restricted to a local Jewish community. With the understanding that New Covenant Christians could worship God from any city or country on the globe, there would be no longer a need for national temple worship. Christ taught Paul that this nationalistic form of temple worship was fading from view (Heb. 8:13).
The apostle Paul understood that the change was now, the day of Pentecost of Acts 2. He didn't have to wait until the destruction of the temple to teach that we can worship God in spirit and in truth whether in Bangkok, London, New York, Lisbon or Moscow. He started immediately to teach Gentile converts the spiritual application of God's law. After the inception of the New Covenant on the day of Pentecost, neither Jew nor Gentile was ever required to go to Jerusalem to worship. God could now be worshipped any place on the globe where people sought to worship Him in SPIRIT and in TRUTH.
