Christ is become of no effect unto you, whosoever of you are justified by the law; you are fallen from grace.
All Commentaries on Galatians 5:4 Go To Galatians 5
Gaius Marius Victorinus
AD 400
All the virtue of the one who believes in Christ is by the grace of God. Grace is not from merits but from readiness to believe God. Therefore [Paul writes] “You have already fallen from grace if you place your justification in the law, because (for example) you serve works, because you observe the sabbath or on account of your circumcision. If you believe that you are justified by this, “you have fallen from grace and been made void of Christ.” You no longer have your faith from Christ nor hope for grace for yourselves from his passion and resurrection, if you believe that justification comes from the law.” .
