This is what is being taught in the book of Hebrews. It teaches of the superiority of the new covenant in Jesus. It relies on a familiarity with the Torah and the commands set forth there.
Therefore, leaving the elementary principles of the doctrine of Christ, let us go on to maturity, not laying again a foundation of repentance from dead works and of faith toward God, of instruction about washings, the laying on of hands, the resurrection of the dead, and eternal judgment. This we will do if God permits.Hebrews 6:1–3 — Modern English Version (Thinline Edition.; Lake Mary, FL: Passio, 2014)
In other words…
Therefore, since Jesus is better let’s be moving forward and not forsaking those Old Testament things that were the foreshadows of Jesus. These are called here the elementary principles of the doctrine of Christ. Let us go on that is keep going–pressing forward – on to maturity. That is, let us be carried to salvation.
Don’t lay again a foundation for yourselves of those foreshadows, the ordinances that pointed forward to Jesus. These were commands of repentance given in the Old Testament laws to be pure and righteous.
Let’s not just put our faith toward God the Father but in Jesus. The Father is revealed in the Son.
Let’s not wander back to the instruction about washings. This is not baptism but the ceremonial washings prescribed in the law.
Let’s not continue the laying on of hands. This is not laying hands on brothers and sisters in prayer. It is pointing to the symbolic imputation of sins that was done by the priest and the one offering a sacrifice for sins.
Let’s clearly understand the resurrection of the dead, and eternal judgment. Not being entangled in Pharisee and/or Sadducee teachings.
Jesus is best. He is the only Way to heaven. The only real Salvation.
