Layers of intent, Paul’s “bondage” has multiple applications
Galatians 5:1 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage. (KJV)
In the freedom, then, with which Christ did make you free -- stand ye, and be not held fast again by a yoke of servitude; (YLT)
Apostle Paul was directly correlating “the yoke of bondage” or “servitude” to being compelled by legalism to take on the outward signs of piety by making physical changes to one’s body. He was talking about circumcision.
