The Greek TR is not perfect nor inspired, and neither was the Kjv!The truth is God’s promise to preserve His word should act as a check and balance on men printing whatever they want and then calling their changes to His word His word. God even placed restrictions on adding to or removing from His word, which men have ignored. There are warnings in scripture placed there by God for men who change His word, and eventually they will stand before God and give an account for their disobedience.
