'Apostleship' in the Bible

to assume the task of this service and apostleship from which Judas turned aside to go to his own place."

Through him we have received grace and our apostleship to bring about the obedience of faith among all the Gentiles on behalf of his name.

If I am not an apostle to others, at least I am to you, for you are the confirming sign of my apostleship in the Lord.

(for he who empowered Peter for his apostleship to the circumcised also empowered me for my apostleship to the Gentiles)
