Paul in his letter to the Galatians 6:17: the sound cicatrici stigma?

Ciao. I wanted to ask you what Paul refers to in the letter to Galati 6:17 rigurdo it “scars”: they are proof of the existence of stigmata or must be interpreted in another way?

The signs spoken of are not external signs, in fact it also speaks of the circumcision of the Jews which is an external sign and says that Christians instead carry the sign of Christ, the inner one, that is, the faith and the blood which washed away sins and redeemed. This is the meaning of the passage you quote.
