For I bear on my body the tattoos of Christ
"Like the Greeks and Romans, modern man dislikes the marking of the human skin, but the Galatians may readily have seen in Paul's words (Gal 6:17) an allusion to the religious tattoos which were held in honour in Asia Minor. They at least would not have been surprised at the idea that the apostle bore the name of Jesus tattooed on his skin." (J. Ysaebert, Greek Baptismal Terminology, 1962, p. 284)
