When any person starts talking Scripture and begins quoting the New Testament, that person does not understand that The New Testament is the retelling and spreading of the Scriptures (teachings of God) given to man. Yes Paul was inspired but what he was writing was the correction of Scripture that were confused and perverted by the Sanhedrin. The term Scriptures actually refer to the Old Testament or the Tanakh, the Hebrew writings also called the Mikra. The Scripture is what Jesus taught and made it more understandable to the Jewish nation at the time while correcting the man made traditions and perversions of the Father’s Truth. The Disciples spread the Gospel truth of Jesus which was a retelling of the Scriptures. The letters of the New Testament Canon were the follow up check in through instruction, praise, and admonition for the peoples of whom heard and believed.
For example, Paul’s words in Galatians 2:20, , “I have been crucified with Messiah. It is no longer I who live, but the Messiah who lives in me. And the life I know live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me”. That is a confession on how the truth in Scripture worked in Paul’s life. You see, God wants communion with each one personally and that was attained through the final blood sacrifice, the ultimate showing of God’s Love. God started the blood sacrifice when He gave Adam and Eve the hair and skin of the innocent lamb to cover their nakedness (they were still vegetarians and only used the wool for clothing). He completed it with the sacrifice of the sinless one, His own Son, the Word Made Flesh, Jesus. But we are still not there and that is why Jesus must return to complete the process of ridding sin and death from the world.
So what is the Tanakh? First is the Torah (Law) which can be interpreted as a teaching or the theory of God. It consists of the Pentateuch, the first five books also found in the Christian Old Testament. The second part of Scripture is called the Nevi’im or Book of Prophets to whom God spoke His teachings and gave praise and warnings of what will happen if the people continued in faith or disobedience. They also were presented with information of the future Kingdom of God. The third part is the Ketuvim, or writings. Basically the histories and wisdom books. The Tanakh concludes with Daniel, Ezra, Nehemiah, and both books of the Chronicles of the Kings. So together Scripture is Torah, Nevi’im, and Ketuvim, the Tanakh.
The New Testament is the sharing of how God ensured His Word was sent to the world which was originally intended to be the mission of the Israelites. They are still God’s Chosen People and we are still Gentile but we are commissioned to ensure God’s Word through Jesus gets to all mankind. This means we have to understand the Scripture as it was intended. A bit ago I wrote on King Josiah and the first great revival. That would have almost worked if the priests had not gone back to their old ways and stayed with the traditions. This being said, the New Covenant through Jesus was still necessary to get Israel back on track. The first people that Jesus transformed were Jewish then those transformed were commissioned to share the Word with the world. That commission then falls on all who hear, understand, and accept the Truth of Scripture which is where we come in.
So we are under the New Covenant but must adhere to the Scripture minus the ceremonial (blood sacrifice, sin offering) laws. Yes that means we must adhere to the Ten Commandments and moral laws. Remember, Jesus condensed the Ten down to the basic two which still spoke of the ten of which we are still bound. We are remade and found in Jesus to become one in communion with the Father as originally intended.
