The church must be reminded that it is not the master or the servant of the state, but rather the conscience of the state. It must be the guide and the critic of the state, and never its tool. If the church does not recapture its prophetic zeal, it will become an irrelevant social club without moral or spiritual authority. If the church does not participate actively in the struggle for peace and for economic and racial justice, it will forfeit the loyalty of millions and cause men everywhere to say that it has atrophied its will.
But if the church will free itself from the shackles of a deadening status quo, and, recovering its great historic mission, will speak and act fearlessly and insistently in terms of justice and peace, it will enkindle the imagination of mankind and fire the souls of men, imbuing them with a glowing and ardent love for truth, justice, and peace. Men far and near will know the church as a great fellowship of love that provides light and bread for lonely travellers at midnight.
