Starting then anew from Tarsus, Paul and Silas set out upon an enormous journey, penetrating, as few modern travellers even now do, from the south-eastern extremity of Asia Minor to the north-western coast, a journey which, with its necessarily prolonged delays, must have taken them at least a year and a half. St. Paul seems to have carefully availed himself of the Roman road system. We are merely given the very barest outline of the course which he pursued, but then when we take up the index maps of Asia Minor inserted in Ramsay's _Historical Geography of Asia Minor_, showing the road systems at various periods, we see that a great Roman road followed the very route which St. Paul took. It started from Tarsus and passed to Derbe, whence of course the road to Lystra, Iconium, and Antioch had already been traversed by St. Paul.[135] He must have made lengthened visits to all these places, as he had much to do and much to teach. He had to expound the decree of the Apostolic Council, to explain Christian truth, to correct the errors and abuses which were daily creeping in, and to enlarge the organisation of the Christian Church by fresh ordinations. Take the case of Timothy as an example of the trouble St. Paul must have experienced. He came to Derbe, where he first found some of the converts made on his earlier tour; whence he passed to Lystra, where he met Timothy, whose acquaintance he had doubtless made on his first journey. He was the son of a Jewess, though his father was a Gentile. St. Paul took and circumcised him to conciliate the Jews. The Apostle must have bestowed a great deal of trouble on this point alone, explaining to the Gentile portion of the Christian community the principles on which he acted and their perfect consistency with his own conduct at Jerusalem and his advocacy of Gentile freedom from the law. Then he ordained him. This we do not learn from the Acts, but from St. Paul's Epistles to Timothy. The Acts simply says of Timothy, "Him would Paul have to go forth with him." But then when we turn to the Epistles written to Timothy, we find that it was not as an ordinary companion that Timothy was taken. He went forth as St. Paul himself had gone forth from the Church of Antioch, a duly ordained and publicly recognised messenger of Christ. We can glean from St. Paul's letters to Timothy the order and ceremonies of this primitive ordination. The rite, as ministered on that occasion, embraced prophesyings or preachings by St. Paul himself and by others upon the serious character of the office then undertaken. This seems plainly intimated in 1 Tim. i. 18: "This charge I commit unto thee, my child Timothy, according to the prophecies which went before on thee"; while there seems a reference to his own exhortations and directions in 2 Tim. ii. 2, where he writes, "The things which thou hast heard from me among many witnesses, the same commit thou to faithful men."
