Autograph postscript. Large letters need not be literally meant in late Greek; but what else can the word mean here? How large a letter (AV) is not a legitimate translation. Probably the reason is bad sight (cf. Galatians 4:15), possibly desire for emphasis; as we print in italics or capitals. A very unfavourable estimate of the moral character of the Judaizers is added. They are not really in earnest in their campaign. They are far from being strict Jews personally, but they pride themselves on making proselytes. The true Christian glories in no flattering successes only in that cross of Christ which brings our old life to a close and separates us for ever from the world. Those thus crucified with Christ and new-created in His resurrection are God's true Israel (cf. Psalms 73:1) whether they be Jew or Gentile.

Galatians 6:11-16
11 Ye see how large a letter I have written unto you with mine own hand.
12 As many as desire to make a fair shew in the flesh, they constrain you to be circumcised; only lest they should suffer persecution for the cross of Christ.
13 For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh.
14 But God forbid that I should glory, save in the cross of our Lord Jesus Christ, by whoma the world is crucified unto me, and I unto the world.
15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
16 And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.
