Why didn't you post the rest of the scripture I referenced?
4:11 I am afraid of you, lest I have bestowed upon you labour in vain.
After hearing the gospel preached, Paul is telling them that he is concerned that they understand nothing about Jesus. They cling to the old way of life, the shadows as opposed to the true light.
The word elements comes from root words meaning a cooling as in end of summer, or a chill.
Galatians is written to Jewish Christians: 4:9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage ? 4:10 Ye observe days, and months, and times, and years. 4:11 I am afraid of you, lest I have bestowed upon you labour in vain. Philippians 3:1-3. 3:2 Beware of dogs, beware of evil workers, beware of the concision. 3:3 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh. Just to be clear, do you believe that Paul is calling holy days that the almighty eternal God created, such as the day of atonement, "weak and beggarly elements"?
