If we strictly interpret Luke's words ('I _have_ called them'), a previous intimation from the Spirit had revealed to them the sphere of their work. In that case, the _separation_ was only the recognition by the brethren of the divine appointment. The inward call must come first, and no ecclesiastical designation can do more than confirm that. But the solemn designation by the Church identifies those who remain behind with the work of those who go forth; it throws responsibility for sympathy and support on the former, and it ministers strength and the sense of companionship to the latter, besides checking that tendency to isolation which accompanies earnestness. To go forth on even Christian service, unrecognised by the brethren, is not good for even a Paul.
But although Luke speaks of the Church sending them away, he takes care immediately to add that it was the Holy Ghost who 'sent them forth.' Ramsay suggests that 'sent them away' is not the meaning of the phrase in verse 3, but that it should be rendered 'gave them leave to depart.' In any case, a clear distinction is drawn between the action of the Church and that of the Spirit, which constituted Paul's real commission as an Apostle. He himself says that he was an Apostle, 'not from men, neither through man.'
II. The events in the first stage of the journey are next summarily presented. Note the local colouring in 'went _down_ to Seleucia,' the seaport of Antioch, at the mouth of the river. The missionaries were naturally led to begin at Cyprus, as Barnabas's birthplace, and that of some of the founders of the church at Antioch.
So, for the first time, the Gospel went to sea, the precursor of so many voyages. It was an 'epoch-making moment' when that ship dropped down with the tide and put out to sea. Salamis was the nearest port on the south-eastern coast of Cyprus, and there they landed,--Barnabas, no doubt, familiar with all he saw; Saul probably a stranger to it all. Their plan of action was that to which Paul adhered in all his after work,--to carry the Gospel to the Jew first, a proceeding for which the manner of worship in the synagogues gave facilities. No doubt, many such were scattered through Cyprus, and Barnabas would be well known in most.
They thus traversed the island from east to west. It is noteworthy that only now is John Mark's name brought in as their attendant. He had come with them from Antioch, but Luke will not mention him, when he is telling of the sending forth of the other two, because Mark was not sent by the Spirit, but only chosen by his uncle, and his subsequent defection did not affect the completeness of their embassy. His entirely subordinate place is made obvious by the point at which he appears.
Nothing of moment happened on the tour till Paphos was reached. That was the capital, the residence of the pro-consul, and the seat of the foul worship of Venus. There the first antagonist was met. It is not Sergius Paulus, pro-consul though he was, who is the central figure of interest to Luke, but the sorcerer who was attached to his train. His character is drawn in Luke's description, and in Paul's fiery exclamation. Each has three clauses, which fall 'like the beats of a hammer.' 'Sorcerer, false prophet, Jew,' make a climax of wickedness. That a Jew should descend to dabble in the black art of magic, and play tricks on the credulity of ignorant people by his knowledge of some simple secrets of chemistry; that he should pretend to prophetic gifts which in his heart he knew to be fraud, and should be recreant to his ancestral faith, proved him to deserve the penetrating sentence which Paul passed on him. He was a trickster, and knew that he was: his inspiration came from an evil source; he had come to hate righteousness of every sort.
