What are the tests to be an Apostle?

Some early manuscripts of Mark 3:14 indicate that the twelve disciples by appointment also were named apostles. In Acts 1:2 and 26, the original disciples are called the apostles.

According to Paul's letter to the church at Ephesus, that church was built upon a foundation of apostles and prophets, Ephesians 2:19-22.

But the New Testament expands the use of apostles beyond just the twelve disciples. Paul (Galatians 1:1), Barnabus (Acts 14:14), James - Jesus' brother (Galatians 1:19), and others (Romans 16:7) are referred to as "apostles". Therefore, the term "apostles" is applied to those who were authentically and specifically called and sent by Christ to be His spokespersons.

One sign of being an apostle was the ability to perform miracles as recorded in 2 Corinthians 12:11-12 andHebrews 2:2-4. BUT be aware that false prophets also may do miracles as in Mark 13:21-23, 2 Thessalonians 2:8-10, and Revelation 13:11-13 (beast of the earth). The test of a true apostle is if they do not deny Jesus as Lord and if they are not "in it" for selfish gain (2 Corinthians 11:5-15 and 2 Corinthians 12:11-12).
