First, it would be impossible for any contemporary Christian to meet the biblical qualifications required for someone to be considered an apostle. The New Testament articulates at least three necessary criteria: 1. an apostle had to be a physical eyewitness of the resurrected Christ (Acts 1:22; 10:39–41; 1 Cor. 9:1; 15:7–8); 2. an apostle had to be personally appointed by the Lord Jesus Christ (Mark 3:14; Luke 6:13; Acts 1:2, 24; 10:41; Gal. 1:1); and 3. an apostle had to be able to authenticate his apostolic appointment with miraculous signs (Matt. 10:1–2; Acts 1:5–8; 2:43; 4:33; 5:12; 8:14; 2 Cor. 12:12; Heb. 2:3–4).
