If to others I am not an apostle, yet at least I am to you; for the seal of mine apostleship are ye in the Lord.

If to others I am not an Apostle, at least I am one to you: for the fact that you are Christians is the sign that I am an Apostle.

Αν δεν ημαι εις αλλους αποστολος, αλλ' εις εσας τουλαχιστον ειμαι· διοτι η σφραγις της αποστολης μου σεις εισθε εν Κυριω.

If I be not an apostle unto others, yet doubtless I am to you: for the seal of mine apostleship are ye in the Lord.
