One of the very greatest evils of present-day religious life, it seems to me, is the reception into the Church of persons who merely repeat a form of words such as “I accept Christ as my personal Saviour,” without giving the slightest evidence to show that they know what such words mean. As a consequence of this practice, hosts of persons are being received into the Church on the basis, as has been well said, of nothing more than a vague admiration for the moral character of Jesus, or else on the basis of a vague purpose of engaging in humanitarian work. One such person within the Church does more harm to the cause of Christ, I for my part believe, than ten such persons outside; and the whole practice ought to be radically changed. The truth is that the ecclesiastical currency in our day has been sadly debased; Church membership, as well as Church office, no longer means what it ought to mean. In view of such a situation, we ought, I think, to have reality at least; instead of comforting ourselves with columns of church statistics, we ought to face the facts; we ought to recall this paper currency and get back to a standard of gold.
To that end, it should, I think, be made much harder than it now is to enter the Church: the confession of faith that is required should be a credible confession; and if it becomes evident upon examination that a candidate has no notion of what he is doing, he should be advised to enter upon a course of instruction before he becomes a member of the Church. Such a course of instruction, moreover, should be conducted not by comparatively untrained laymen, but ordinarily by the ministers; the excellent institution of the catechetical class should be generally revived. Those churches, like the Lutheran bodies in America, which have maintained that institution, have profited enormously by its employment; and their example deserves to be generally followed.
