For in the first place, such care was commanded from the outset. Christ has promised that His truth shall continue and shall prevail. But He has not exempted Christians from the duty of preserving and propagating it. He, Who is the Truth, has declared that He is ever with His Church, even unto the end of the world (Matt. xxviii. 20); and in fulfilment of this promise He has bestowed the Spirit of truth upon it. But He has nowhere hinted that His Church is to leave the cause of His Gospel to take care of itself. On the contrary, at the very time that He promised to be alway with His disciples, He prefaced this promise with the command, "Go ye therefore, and make disciples of all the nations, ... teaching them to observe all things whatsoever I commanded you;" as if His promise were contingent upon their fulfilment of this charge. At the very moment when the Church received the truth, it was told that it had the responsibility of safeguarding it and making it known.
And, secondly, experience has proved how entirely necessary such care is. The Gospel cannot be superseded by any announcement possessing a larger measure of truth and authority. So far as the present dispensation goes, its claims are absolute and final. But it may be seriously misunderstood; it may be corrupted by large admixture of error; it may be partially or even totally forgotten; it may be supplanted by some meretricious counterfeit. There were Thessalonians who had supposed that the Gospel exempted them from the obligation of working to earn their bread. There were Christians at Corinth and Ephesus who had confounded the liberty of the Gospel with antinomian license. There was the Church of Sardis which had so completely forgotten what it had received, that no works of its doing were found fulfilled before God, and the remnant of truth and life which survived was ready to perish. And the Churches of Galatia had been in danger of casting on one side the glories of the Gospel and returning to the bondage of the Law. Through ignorance, through neglect, through wilful misrepresentation or interested opposition, the truth might be obscured, or depraved, or defeated; and there were few places where such disastrous results were more possible than at Ephesus. Its restless activity in commerce and speculation; its worldliness; the seductiveness of its forms of paganism;--all these constituted an atmosphere in which Christian truth, unless carefully protected, would be likely to become tainted or be ignored. Even without taking into account the proposal that Timothy should leave Ephesus for awhile and visit the Apostle in his imprisonment at Rome, it was no more than necessary precaution that he should endeavour to secure the establishment of a permanent centre for preserving and handing on in its integrity the faith once for all committed to the saints.
"The things which thou hast heard from me among many witnesses." The last three words are remarkable; and they are still more remarkable in the original Greek. St. Paul does not say simply "_in the presence of_ many witnesses" (=enôpion= or =parontôn pollôn martyrôn=) but "_by means of_ many witnesses" (=dia pollôn martyrôn=). In the First Epistle (vi. 12) he had appealed to the good confession which Timothy had made "in the sight of many witnesses." As regards Timothy's confession these were witnesses and no more. They were able for ever afterwards to testify that he had made it; but they did not help him to make it. The confession was his, not theirs, although no doubt they assented to it and approved it; and their presence in no way affected its goodness. But here those who were present were something more than mere witnesses of what the Apostle said to Timothy; they were an integral part of the proceeding. Their presence was an element without which the Apostle's teaching would have assumed a different character. They were not a mere audience, able to testify as to what was said; they were guarantees of the instruction which was given. The sentiments and opinions which St Paul might express in private to his disciple, and the authoritative teaching which he delivered to him in public under the sanction of many witnesses, were two different things and stood on different grounds. Timothy had often heard from his friend his personal views on a variety of subjects; and he had often heard from the Apostle his official testimony, delivered solemnly in the congregation, as to the truths of the Gospel. It is this latter body of instruction, thus amply guaranteed, of which Timothy is to take such care. He is to treat it as a treasure committed to his charge, a precious legacy which he holds in trust. And in his turn he is to commit it to the keeping of trustworthy persons, who will know its value, and be capable of preserving it intact and of handing it on to others as trustworthy as themselves.
