You have two passages and two different problems:
I marvel that ye are (G3346 μετατίθημι) so soon removed (G3346 μετατίθημι) from him that called you into the grace of Christ unto another gospel: (Galatians 1:6)
For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning (G3346 μετατίθημι) the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ. (Jude 1:4)
The Galatians passage is warning against drifting into legalism and Jude is warning that certain men have crept in unawares who would turn grace in the licentiousness. The Gentiles in Galatia were being influenced by Judaizers and practicing some of the Jewish practices. Paul is saying your turning here from Christ to the beggarly elements of the Law. Jude has to deal with the other extreme, walking along the narrow path there are two ditches. One is legalism and the other licentiousness, does it really matter which ditch you fall into?
