God communicated with the devout prophets and teachers in the church at Antioch. “As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.” Acts 13:2. These apostles were therefore dedicated to God in a most solemn manner by fasting and prayer and the laying on of hands; and they were sent forth to their field of labor among the Gentiles. SR 303.1
Both Paul and Barnabas had been laboring as ministers of Christ, and God had abundantly blessed their efforts, but neither of them had previously been formally ordained to the gospel ministry by prayer and the laying on of hands. They were now authorized by the church not only to teach the truth but to baptize and to organize churches, being invested with full ecclesiastical authority. This was an important era for the church. Though the middle wall of partition between Jew and Gentile had been broken down by the death of Christ, letting the Gentiles into the full privileges of the gospel, the veil had not yet been torn away from the eyes of many of the believing Jews, and they could not clearly discern to the end of that which was abolished by the Son of God. The work was now to be prosecuted with vigor among the Gentiles, and was to result in strengthening the church by a great ingathering of souls. SR 303.2
The apostles, in this, their special work, were to be exposed to suspicion, prejudice, and jealousy. As a natural consequence of their departure from the exclusiveness of the Jews, their doctrine and views would be subject to the charge of heresy; and their credentials as ministers of the gospel would be questioned by many zealous, believing Jews. God foresaw all these difficulties which His servants would undergo, and, in His wise providence, caused them to be invested with unquestionable authority from the established church of God, that their work should be above challenge.

The ordination by the laying on of hands was, at a later date, greatly abused; unwarrantable importance was attached to the act, as though a power came at once upon those who received such ordination, which immediately qualified them for any and all ministerial work, as though virtue lay in the act of laying on of hands. We have, in the history of these two apostles, only a simple record of the laying on of hands, and its bearing upon their work. Both Paul and Barnabas had already received their commission from God Himself; and the ceremony of the laying on of hands added no new grace or virtual qualification. It was merely setting the seal of the church upon the work of God—an acknowledged form of designation to an appointed office. SR 304.2
