Ministers of Christ, images of the Lord.

But we all, with unveiled face giving back as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as from the Lord who is the Spirit.
2 Corinthians 3:18

Apostolic Ministry

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.
1 Corinthians 9:2
