What are the qualifications for an apostle?

The qualification for apostleship, according to the Bible, includes being sent on an errand or to deliver a message from God. The word apostle means one sent on a mission. Jesus himself was an apostle, as God sent him to deliver his message.

Jesus also had apostles in addition to being one. He hand-selected 12 men to hold apostleship; however, the criteria he used to select them was never disclosed. The apostle Peter later devised a list of characteristics that one must possess to be considered for an apostleship, which included having witnessed Jesus' death on the cross, having walked and talked with him, and having witnessed his baptism.
