What the Galatians heard was Torah.
As Peter wrote, many are lost by wresting with Paul’s words; do not let that happen to you.
The Galatians had been led away from Torah and into the Pharisees’ false ‘oral’ law.
Following the pharisees was a common problem all around the Mediterranean.
The pastors of most churches today are pharisees of a sort, preaching a man made religion called christianity, rather than the faith that Yeshua’s netzerim followed.
You are ... lost, directly contradicting The Bible, The Word of God. Just read what Paul wrote. Get Rood out of your head.
