If the Church is to maintain its Holiness, it must of necessity be to some extent separated from the world; it cannot mix as a Church in all worldly activities. It cannot simply set itself out to permeate the general life of men, maintaining nothing that is separate and apart for itself. If it does that, it will simply be lost in the general life of the world. In the last resort our characters depend almost entirely upon the influences that play upon them in our environment; the one place where we have effective choice is in determining the influences to which we will submit ourselves. If there is no place in our society, or in the world, where men may count upon finding the power of God in purity, then men will inevitably fail to rise above that sort of character, which their worldly environment happens to be forming in them. The Church then, precisely in order to do this work in the world, must keep itself in some sense separate from the world; but the vast majority of its members are people in the daily life of the world, pursuing their avocations there; and it would plainly be wholly disastrous to require that all Christian people, in virtue of their Christianity, should withdraw themselves from the ordinary concerns of men. There is, therefore, no means by which this separateness of the Church can be achieved unless there are certain persons set apart to be representatives of the Church, and of the Church only; and who, because they are official representatives of the Church are thereby deprived of the right to take part in many worldly activities, though these in themselves are right enough. It is not because they are more truly members of the Church than others, nor because there is a different moral standard for clergy and laity, but because in the whole life of the Church there are certain functions which are incompatible with others, just as in the State a man cannot be at the same time an advocate and a judge, or commander-in-chief and ambassador. Thus, for example, as it seems to me, one who is called to be a priest of the Church, inevitably forfeits the right to take part in the hurly-burly of party politics; partly because, in a world which consists of many parties, he is responsible for bringing before men the claim of God to which all the parties ought to bow; partly also because a man’s activities inevitably affect the quality of his own mind, and if we are to be as it were repositories of the Eternal truths, if we are to have ready for dispensation all the treasures which God commits to His Church, we need a type of mind which cannot, at least by most men, be maintained, if we are engaged in heated controversy and frequent debate.
