Joseph Barber Lightfoot in his Commentary on the Epistle to the Galatians writes: "At this point [Gal 6:11] the apostle takes the pen from his amanuensis, and the concluding paragraph is written with his own hand. From the time when letters began to be forged in his name (2 Thess 2:2; 3:17) it seems to have been his practice to close with a few words in his own handwriting, as a precaution against such forgeries... In the present case he writes a whole paragraph, summing up the main lessons of the epistle in terse, eager, disjointed sentences. He writes it, too, in large, bold characters (Gr. pelikois grammasin), that his handwriting may reflect the energy and determination of his soul."
