Today is the feast of the heroic St. Barnabas. He was the apostle (not one of the Twelve, though) who vouched for the sincerity of the persecutor Saul's conversion, and got him accepted into the community of believers. And then when Saul's overweening zeal (!) caused problems for the community, who invited him to go home to Tarsus, it was Barnabas who traveled there to find him and invite him to minister in Antioch. It was from Antioch that Barnabas, the leader, and his companion, Saul, set out to evangelize. And it was on that "first missionary voyage" that Barnabas, the leader and Apostle, ceded to Paul, the Apostle of the Gentiles.
Barnabas' great quality was that he could recognize the presence and action of God in the most unlikely circumstances. He recognized God's power at work in Saul the former persecutor. He recognized the power of the Spirit in the conversion of pagans to the Gospel in Antioch. And when Saul began to outshine him in preaching the Gospel, he recognized the grace of God there, too, and let Paul the Apostle "increase" while he decreased.
All together, you can really understand why this man's nickname was "Son of Consolation."
