Carl, any church who fits the bill of preaching another gospel but the same ( or looks the same but really is not). Galatians and 2 Corinthians is rich with these warnings. We even see it in the Gospels ( synoptic) Jesus speaking.
Mark 7:9 . We have to be weary of another spirit in the churches ( any church), actually evil spirit in reality. We see it ( the warning) in the book of Acts. Bottom line: a false gospel.
In Mark 7:9, Jesus criticized the Pharisees as being hypocrites for setting aside the commands of God in order to establish their own traditions, so it is important to distinguish between the two, but then you interpret what was only said against obeying the traditions of men as being against obeying laws that are the commands of God.
Grace is also no longer grace if you are going to observe the old customs for salvation.
Galatians 5:4 You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace.
We do not earn our salvation by obeying God's law because it was never given for that purpose, but that doesn't mean that we shouldn't obey it for the purposes for which it was given. All throughout the Bible, God wanted His people to repent and to return to obedience to His law, and even Jesus began his ministry with that message, so it would be absurd to interpret Galatians 5:4 as Paul warning us from doing that and saying that we will be cut off from Christ if we follow Christ.
Furthermore, in Psalms 119:29, David wanted God to be gracious to him by teaching him to obey His law, and it would be absurd to think that David wanted God to be gracious to him by teaching him how to fall from grace. Likewise, in Romans 1:5, we have received grace in order to bring about the obedience of faith, but we have not received grace in order to bring about our fall from grace. In Titus 2:11-14, our salvation is described as being trained by grace in order do what is godly, righteous, and good, and to renounce doing what is ungodly, which is what God's law was given to instruct how to do, so God graciously teaching us to obey His law is itself part of the content of His free gift of salvation, and participating in that training does nothing to earn it, but rather that is what it looks like to receive it. And again, it would be absurd to think that our salvation involves being trained by grace to fall from grace.
Paul's problem in Galatians was not with those who were teaching Gentiles how to obey God's law in accordance with Christ's example as if following Christ was somehow a negative thing, but rather his problem was with those who were wanting to require Gentiles to obey their works of the law in order to become saved.
And
Romans 11:6 And if by grace, then it cannot be based on works; if it were, grace would no longer be grace.
Grace is a free gift, which is incompatible with doing works done to earn something, as Romans 11:6 is contrasting, however, works can be done for other reasons that are not incompatible with grace. For example, in James 2:17-18, he said that faith without works is dead and he would show his faith by his works, so doing works in obedience to God is what faith looks like, not about trying to earn something. Or the content of a free gift can itself be being taught how to do something, such as being taught how to play an instrument as a free gift from a profession musician, and so being taught how to obey God's law is itself part of the content of God's free gift of salvation. Our salvation is from sin and sin is the transgression of God's law (1 John 3:4), so being trained by grace to live in obedience to God's law through faith is what it looks like to receive the free gift of Jesus saving us from living in transgression of God's law.
