The book of Galatians was written to and for Israel. This will be just a brief look at the easiest verses to show this truth. Galatians is one of the more abused books where people pull a scripture like Galatians 3:28 out of context. Take a look at Galatians 3:7.
“Know ye therefore that they which are of faith, the same are the children of Abraham.”
So modern Christianity has been taught to read that verse as the following.
“Know ye therefore that they which are of faith, the same are become the children of Abraham.”
However here is the logical equivalent statement (contrapositive) of what Paul wrote and the understanding he intended.
“If you are not the children of Abraham, then ye are not they which are of faith.”
The standard teaching is to spiritualize scripture to make it more inclusive. Doing so destroys the meaning intended by the author. So with spiritualization one must ask if Paul just did not understand what God wanted him to write or if God didn’t know what was going to happen or if God did, but then He changed his mind and broke promises He made and became a liar. Spiritualizing verses makes God a promise breaker and a liar.
Here is another verse from chapter 3.
3:29 “And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.”
Here is the logical equivalent statement.
“If ye be not Abraham’s seed, or not heirs according to the promise, then ye are not Christ’s.”
Both of these statements are found in the same chapter where verse 28 is abused through inclusion.
“There is neither Judean nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.”
Verse 28 really doesn’t prove what most have been taught at all. There were Judean Israelites and Greek Israelites at the time of Paul. This verse must be understood in light of the context of the surrounding verses. To pull it out of context and change the people in the verse to be all people everywhere is dishonest.
Chapter four is even easier to prove the book is written to Israel through the use of scripture’s defined words.
Galatians 4:3 “Even so we, when we were children, were in bondage under the elements of the world”.
Christ himself defined the word children as meaning Israelites.
Matthew 15:26 “But he answered and said, It is not meet to take the children’s bread, and to cast it to dogs.”
Christ also defined the word dog here and the woman of Canaan accepted it.
Galatians 4:4-5 “But when the fullness of the time was come, God sent forth his Son, made of a woman, made under the law, To redeem them that were under the law, that we might receive the adoption of sons.”
In verses 4 and 5 Paul mentions the Law of God. No other people were given the Law except Israel and would have no understanding or knowledge of it. Psalms 147:19-20. Only Israel was under the Law.
Redemption can only be for those who were once in good standing with God, which was only Israel. Redemption is only for next of kin by the Law of the Kinsman Redeemer. This is why so much time was spent showing the lineage of Christ in relation to Israel. See the family listings in Matthew 1 and Luke 3.
The adoption belongs only to Israel.
Romans 9:4 “Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;”
When you see those words along with others like special treasure or peculiar treasure, grapes, olives, called, elect, heirs and sheep you know that it is symbolic for Israel. The bible defines its own terms. There is never any verse that equates non-Israelites with those terms. Remember the Latin word Gentile only means nation. It must be understood in context as to the who. If scripture says that some Gentiles are called then you know that they are of physical Israel by scripture definition and usually of the dispersed ten tribes. Paul never changed God’s definitions. Paul only used God’s words the way God intended.
The Greek word for our English word adoption is not found in the new testament. The Greek word means placement of sons, that is placement of those who are already natural sons.
There is more that you can find when you read Galatians. Paul was not double minded and he knew his audience. The modern day Jews are not Israelites. Think about it.
