The Liberal notion that religion was a matter of private belief and of conduct in private life, and that there is no reason why Christians should not be able to accommodate themselves to any world which treats them good-naturedly, is becoming less and less tenable . . . .We have less excuse than our ancestors for un-Christian conduct, because the growth of an un-Christian society about us, its more obvious intrusion upon our lives, has been breaking down the comfortable distinction between public and private morality. The problem of leading a Christian life in a non-Christian society is now very present to us . . . . It is not merely the problem of a minority in a society, of individuals holding an alien belief. It is the problem constituted by our implication in a network of institutions from which we cannot dissociate ourselves: institutions the operation of which appears no longer neutral, but non-Christian.And as for the Christian who is not conscious of his dilemma—and he is in the majority—he is becoming more and more de-Christianised by all sorts of unconscious pressure: paganism holds all the most valuable advertising space. Anything like Christian traditions transmitted from generation to generation within the family must disappear, and the small body of Christians will consist entirely of adult recruits . . . .I am not concerned with the problem of Christians as a persecuted minority. When the Christian is treated as an enemy of the State, his course is very much harder, but it is simpler. I am concerned with the dangers to the tolerated minority; and in the modern world, it may turn out that the most tolerable thing for Christians is to be tolerated.
