What I am going to say is not directly unto edification, but indirectly it is so must certainly. Directly it is rather for that instruction which is a need in our Christian life as essential as edification. We cannot do without either. On the one hand instruction with no idea of edification at all becomes mere academical discourse. It may begin anywhere and it may end anywhere. On the other hand, edification without instruction very soon becomes a feeble and ineffective thing. I think a great many of us would be agreed that part of the poverty and weakness of the Church at the present moment is due to the fact that edification has been pursued to the neglect of instruction. We have been a little too prone to dwell upon the simple side of the gospel. All our capital is in small circulation. We have not put by a reserve, as it were. And therefore the simplicity itself has become unsettled and ineffectual, confused and confusing.

I ask your attention to certain aspects of our Christian faith which perhaps do not lie immediately upon the surface, but which are yet the condition of the Church’s continued energy and success in the world. I suppose there is nobody here who does not believe in the Church. At any rate, what I propose to say will be said entirely from that standpoint. We believe in the Holy Catholic Church. My contention would be that, apart from such a position as I desire to bring to your notice – some real apostolic belief in the real work of Jesus Christ – apart from that no Church can continue to exist. That is the point of view which I take at the outset. The Church is precious, not in itself, but because of God’s purpose with it. It is there because of what God has done for it. It is there, more particularly, because of what Christ has done, and done in history. It is there solely to serve the Gospel.
