The natural implication of this phrase is that it has not been long since Paul was with the Galatians and they came to faith in Christ.1 In that case, they are leaving the truths that he proclaimed but a short time after he proclaimed those truths to them. Alternatively, it could refer to the arrival of the false teachers.2 The Galatians are in the process of transferring their loyalty from God,3 only a short while after the false teachers have arrived in their midst. Paul did not think they would be so easily or quickly deceived.4
6 Je m'étonne que vous vous détourniez si promptement de celui qui vous a appelés par la grâce de Christ, pour passer à un autre évangile.
