Taking a deep breath

Am I not free? Am I not an apostle?

Have I not seen Jesus our Lord? Are you not my work in the Lord?

If I am not an apostle to others, at least I am to you;

for you are the seal of my apostleship in the Lord.

1 Corinthians 9:1-2

This pushed me to personally ask one question. It is this:

If the believing communities I have served are the seal of my apostleship,

do they confirm that I am really of the apostolic ministry?

Let's just say, this question just makes me take a deep breath.
