How this is to be done, of course it requires wisdom to decide, and there will doubtless be different ways for different men and for different times. In a former generation a president of this college[61] preached in the College Chapel straight through the doctrines of Christianity, taking them up one by one in systematic order; and his book was long a model to preachers both in this country and Great Britain. He was preaching to an academic audience, and there are probably few congregations for which such a course would be suitable now; although I know at least one able young minister in a country village who has been pursuing this method from the commencement of his ministry. Once a month he gives a sermon of the course; perhaps his people do not know that he is doing so; but he is giving his own mind the discipline of investigating the doctrines of Christianity in their order; and I am certain both that he himself is growing a strong man in the process and that his people, though unconsciously, are getting the benefit of it. In the Lutheran and Episcopal Churches the observance of the Christian festivals gives occasion for regularly bringing the circle of the grand Christian facts before the minds of the people. We have not this guidance; but a faithful minister is bound to make sure that he is preaching with sufficient frequency on the leading Christian facts and doctrines, and that he is not omitting any essential element of Christianity.[62] Not unfrequently ministers are exhorted to cultivate extreme simplicity in their preaching. Everything ought, we are told, to be brought down to the comprehension of the most ignorant hearer, and even of children. Far be it from me to depreciate the place of the simplest in the congregation; it is one of the best features of the Church of the present day that it cares for the lambs. I dealt with this subject, not unsympathetically I hope, in a former lecture. But do not ask us to be always speaking to children or to beginners. Is the Bible always simple? Is Job simple, or Isaiah? Is the Epistle to the Romans simple, or Galatians? This cry for simplicity is three-fourths intellectual laziness; and that Church is doomed in which there is not supplied meat for men as well as milk for babes. We owe the Gospel not only to the barbarian but also to the Greek, not only to the unwise but also to the wise.[63]
