Elementary Principles

Therefore, leaving the discussion of the elementary principles of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works and of faith toward God, of the doctrine of baptisms, of laying on of hand, of the resurrection of the dead, and of eternal judgment.Hebrews 6:1-3
The Elementary Principles of Christ

What we need to know from this passage is that no one will ever make it to maturity without first understanding the elementary doctrine of Christ. If we cannot recognise the letter "a" in the English alphabet, we would not be able to pronounce all the words that containing an "a". So, we can say that "a" is elementary, and without knowledge of it, we would not be proficient in the English language either in writing or in spoken English.
Without knowing and understanding the elementary principles of Christ, we will never go on to perfection / completeness / maturity, in Christ Yeshua. In other words, people would only be babes, mere men, and unspiritual in Christ and nothing more but Christ wants us to go on to maturity in Him.
The elementary principles (or doctrines) of Christ are the foundation on which our walk with Christ is built. Without this foundation, no one is going to stand upright in the Lord Yeshua.
There are six topics to consider in the elementary doctrine of Christ and they are:

  1. Repentance from dead works
  2. Faith towards God
  3. Baptisms
  4. Laying on of hands
  5. Resurrection of the dead
  6. Eternal judgment
