There are not many passages in the Pastoral Epistles which treat so plainly as this does of doctrine. As a rule St. Paul assumes that his delegates, Timothy and Titus, are well instructed (as he knew they were) in the details of the Christian faith, and he does not stay even to remind them of what he had frequently taught to them and to others in their presence. The purpose of the Epistles is to give practical rather than doctrinal instruction; to teach Timothy and Titus how to shape their own conduct, and what kind of conduct they are chiefly to insist upon in the different classes of Christians committed to their charge. Here, however, and in the next chapter, we have marked exceptions to this method. Yet even here the exception is more apparent than real; for the doctrinal statements are introduced, not as truths to be recognized and believed (it is taken for granted that they _are_ recognized and believed), but as the basis of the practical exhortations which have just been given. It is because these great truths have been revealed, because life is so real and so important, and because eternity is so certain, that Titus is to exert all his influence to produce the best kind of conduct in his flock, whether men or women, old or young, bond or free. The passage before us might almost serve as a summary of St. Paul's teaching. In it he once more insists upon the inseparable connexion between creed and character, doctrine and life, and intimates the close relations between the past, the present, and the future, in the Christian scheme of salvation. There are certain facts in the past, which must be believed; and there is a kind of life in the present, which must be lived; and there are things in store for us in the future, which must be looked for. Thus the three great virtues of faith, charity, and hope are inculcated. Two Epiphanies or appearances of Jesus Christ in this world are stated as the two great limits of the Christian dispensation. There is the Epiphany of grace, when the Christ appeared in humility, bringing salvation and instruction to all men; and there is the Epiphany of glory, when He will appear again in power, that He may claim as His own possession the people whom He has redeemed. And between these two there is the Christian life with its "blessed hope," the hope of the Lord's return in glory to complete the kingdom which His first Advent began. Most of us make far too little of this "blessed hope." It is of incalculable value; first, as a test of our own sincerity and reality; and secondly, as a source of strength to carry us over the difficulties and disappointments which beset our daily course.
