What does the Bible say about the role of an apostle?

An apostle is defined as someone who is appointed by the Lord Jesus Christ and taught directly by Him. Paul emphasizes that his apostleship is not of human origin, but is a divine appointment from Jesus and God the Father, who raised Him from the dead. This unique calling establishes their authority in delivering God's message. Specific passages such as Acts 9, Acts 22, and Acts 26 highlight Paul's transformative experience on the Damascus road, affirming that he received the gospel directly through revelation from Christ rather than through human teaching. Thus, the role of an apostle is foundational for the early church and sets a standard not to be duplicated today.
