IT IS CALLED GNOSTICISM
Gnostics claim to possess an elevated knowledge, a “higher truth” known only to a certain few. Gnosticism comes from the Greek word gnosis which means “to know.” Gnostics claim to possess a higher knowledge, not from the Bible, but acquired on some mystical higher plain of existence. Gnostics see themselves as a privileged class elevated above everybody else by their higher, deeper knowledge of God.
BUT, BE VERY CAREFUL WHEN YOU FORM THESE CLIQUES ... REJECTING OTHERS ... THROWING STUMBLING BLOCKS. SCRIPTURE SAYS,
I COR. 10:11- 12 These things happened to them as examples and were written down as warnings for us, on whom the culmination of the ages has come. 12 So, if you think you are standing firm, be careful that you don’t fall!
PAUL DEALS WITH GNOSTICS IN THE BOOK OF COLOSSIANS:
COLOSSIANS 1:9 For this reason we also, since the day we heard it, do not cease to pray for you, and to ask that you may be filled with the knowledge [epignosin] of His will in all wisdom and spiritual understanding; 10 that you may walk worthy of the Lord, fully pleasing Him, being fruitful in every good work and increasing in the knowledge [epignosin] of God; 11 strengthened with all might, according to His glorious power, for all patience and longsuffering with joy; 12 giving thanks to the Father who has qualified us to be partakers of the inheritance of the saints in the light. (NKJV)
In this passage, Paul begins his attack on the Gnostic beliefs being promulgated to the Colossians. He does so with a few subtle statements that are easily overlooked if the context isn't recognized. Paul states that he and Timothy have been praying for the Colossians, asking God to fill them with knowledge, that they may be fruitful in every good work. In verses 9 and 10, the word "knowledge" comes from the Greek word epignosin. Of this word, Kenneth S. Wuest writes:
The word is an advance upon gnosis (knowledge) in that it denotes a larger and more thorough knowledge. It is a knowledge which grasps and penetrates into an object. It was a favorite word of the Gnostics who used it to designate the superior knowledge which they claimed as their exclusive possession. Paul prays that all the saints might become possessors of this knowledge, indicating that it was open for all to appropriate, not a secret mystery into which only a favored few could be initiated. (p. 175, vol. I, Word Studies in the Greek New Testament, "Ephesians and Colossians")
Paul uses EPIGNOSIN to emphasize the true and full knowledge of God that he wanted the Colossians to attain. The implication is that the knowledge of the Gnostics was neither true nor full. THIS KNOWLEDGE HAS BEEN GIVEN TO EVERY ONE WHO IS A CHILD OF GOD THRU CHRIST.
14 For this cause I bow my knees unto the Father of our Lord Jesus Christ,
15 Of whom the whole family in heaven and earth is named,
16 That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;
17 That Christ may dwell in your hearts by faith; that ye, being rooted and grounded in love,
18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height;
19 And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.
