Galatians 1:6-9 New American Bible (Revised Edition) (NABRE)
II. Loyalty to the Gospel[a]
6 I am amazed that you are so quickly forsaking the one who called you[b] by [the] grace [of Christ] for a different gospel 7 (not that there is another). But there are some who are disturbing you and wish to pervert the gospel of Christ. 8 But even if we or an angel from heaven should preach [to you] a gospel other than the one that we preached to you, let that one be accursed![c] 9 As we have said before, and now I say again, if anyone preaches to you a gospel other than the one that you received, let that one be accursed!
