Luke has given some account of Peter, John, and the two Jameses (Acts 12:2, 17; 15:13; 21:18), but beyond this we know nothing from authentic history of the rest of the original twelve. After the martyrdom of James the Greater (Acts 12:2), James the Less usually resided at Jerusalem, while Paul, “the apostle of the uncircumcision,” usually travelled as a missionary among the Gentiles (Galatians 2:8). It was characteristic of the apostles and necessary (1) that they should have seen the Lord, and been able to testify of him and of his resurrection from personal knowledge (John 15:27; Acts 1:21, 22; 1 Corinthians 9:1; Acts 22:14, 15). (2.) They must have been immediately called to that office by Christ (Luke 6:13; Galatians 1:1). (3.) It was essential that they should be infallibly inspired, and thus secured against all error and mistake in their public teaching, whether by word or by writing (John 14:26; 16:13; 1 Thessalonians 2:13).
