Hardly! Verse 8 says, "Formerly, when you did not know God, you were slaves to those who by nature are not Gods." When was the last time you heard of any Jewish folks who "did not know God?"....at least in New Testament times!
4:10 Ye observe days, and months, and times, and years.
Pagans observed the above.....have you ever heard of the "Venerable Day of the Sun?" There is no mention of Sabbaths or Feast Days in this scripture! Pagans did indeed have "special days".....and months....and years.
Let us review:
The purpose of the letters to the churches, and even though they were addressed to"Galatians" they were circulated throughout all of them. They are even written to us today, and the message is timeless.
Galatians was written to refute the Judaizers and to call people back to the true Gospel.
Chapter1: verse8- 9, is his warning against listening to those who preach any gospel other than the one Paul preached
He proceeds to tell them that he received the Gospel from God, and in chapter 2:4, he says that false brethren were unawares brought in.
In chapter 3, he explains the superiority of the Gospel over all others.
Chapter 3:1, he asks the foolish "Who has bewitched you", so they were getting false information from someone, and it would not be from the Apostles.
Chapter 4, verses 8-20 shows his concern for the deceived.
Chapter 5, he preaches the liberty of the Gospel and here once again, he shows why the Law cannot save.
Chapter 6, verses 11-18 he gives his last warning, especially see verse 13, and again in verse 15, he says that Jesus is all that matters.
To conclude, beware, for false teachers want you to think that Christ's death did not make a final atonement for sin, they say that people must obey the Law in order to be saved, they try to find favor with God by observing certain rituals. When told that he was disregarding the Law of Moses, Paul responds by putting the Law in its proper place. He says it shows people how they sin and points them to Christ.
