Jesus told the disciples to beware of the leaven of the Pharisees, which is their doctrines. The Lord regularly spoke against the traditions of men displacing God’s word as their memorials. This people draw near unto me with their mouth and honor me with their lips, but their heart is far from me, but in vain they do worship me, teaching for doctrines the ordinances of man. Matthew 15:8; Is 29:13.
If talk of firstborn sons, unleavened bread and the Torah given to Moses as the Memorials we maintain before God strikes you as odd, your “bread” may have been leavened by the doctrines of men. Much of Paul’s teaching in regards to the Law has been greatly misconstrued. Paul wrote in Ephesians 2:15 having abolished in His flesh the enmity, “the law of commandments contained in ordinances”…this expression in the Greek nomos entole en dogma refers to the place given to commentary. Dogma in English comes directly from the Greek dogma and refers to the opinion of “experts”. Someone is dogmatic when they are devoted to the teachings of a preferred teacher, preacher or guru.
Therefore let us keep the feast not with old leaven neither with leaven of malice and wickedness, but with the unleavened bread of sincerity and truth. 1 Co 5:8.
Paul gave this testimony of himself at Jerusalem in Acts 22:3,” I am verily a man who is a Jew born in Tarsus in Cilicia yet brought up in this city at the feet of Gamaliel and taught according to the perfect manner of the law of the fathers,” This manner of the law of the fathers went way beyond the study of the law and the prophets, but was thorough in considering the commentaries of experts, known as sages who often interpreted passages in contrary ways.
Paul is even more direct in writing; blotting out the “handwriting” of ordinances (dogma), which was against us (as a testimony to the doctrines of men), which was contrary to us and took it out of the way, nailing it to His stake. Colossians 2:15. This is only evident when we are circumcised by the circumcision of Christ (without hands, in the Spirit not the flesh). That you be not spoiled by the philosophy and tradition of men, which is vain deceit (and conceit), and worldly principles (degrees) which are perishing. Colossians chapter 2 (essential!).
When Paul wrote in Romans 8:3; for what the Law could not do in that it was weak through the flesh, God sending His own Son in the likeness of sinful flesh and for sin, condemned sin in the flesh; the issue is clearly the weakness of the flesh, not the inadequacy of the Law. This was preceded by these key verses in Romans chapter 7. Wherefore the Law is holy and the commandment holy and just and good. Verse 12. For we know that the Law is spiritual but I am carnal, sold under sin. Verse 14. For I delight in the Law of God after the inward man. Verse 22. But I see another law in my members warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. Verse 23. I thank God through Jesus Christ our Lord. So then with the mind I serve the Law of God; but with the flesh the law of sin. Verse 25. In neglecting a correct understanding of Romans 7, many believe that when Paul wrote in Romans 8:2 for the Law of the Spirit of Life in Christ Jesus has made me free from the law of sin and death; that he is somehow referring to the law of Moses! Our carnal man must die for us to fulfill the good and perfect and acceptable Will of God, as expressed by His Torah. Do we then make void the Law through faith? God Forbid! Yea, we establish the Law! Romans 3:31.
For our rejoicing is this, the testimony of our conscience, that in simplicity and godly sincerity not with fleshly wisdom, but by the grace of God we have had our conversation in the world. 2 Co 1:12.
For we are not as many which corrupt the Word of God, but as of sincerity but as of God, in the sight of God we speak in Christ. 2 Co 2:17.
Now therefore fear the Lord and serve Him in sincerity and in truth, and put away the gods which your fathers served on the other side of the flood and in Egypt, and serve the Lord. Joshua 24:14.
