In following the course of thought and feeling which this letter embodies, we have seen the Apostle touch various topics. They rise into view as pastoral care, or friendly feeling, as outward circumstances suggest them. The demands of Christian friendship, the responsibilities of the Christian ministry, the trials of Christian endurance; what is due from an apostle, or from a Church member; how life and death are to be confronted; what is to be done about dangers and faults; how pride and self-will are to be judged and remedied; how the narrow heart is to be rebuked and enlarged; how the life of a disciple is to become luminous and edifying,--in reference to all, and all alike, he speaks from the same central position, and with the same fulness of resource. In Christ revealed, in Christ received and known, he finds the light, and the strength, and the salve, which every case requires. Each new demand unlocks new resources, new conceptions of goodness and of victory. So, in one great passage, in the third chapter, catching fire, as it were, from the scorn with which a religion of externals fills him, he breaks forth into a magnificent proclamation of the true Christianity. He celebrates its reality and intensity as life in Christ--Christ known, found, gained--Christ in the righteousness of faith and in the power of resurrection. He depicts vividly the aspiration and endeavour of that life as it continually presses onward from faith to experience and achievement, as it verifies relations to a world unseen, and looks and hastes towards a world to come. Then the wave of thought and feeling subsides; but its force is felt in the last wavelets of loving counsel that ripple to the shore. One feels that for Paul, who was rich in doctrine, doctrine is after all but the measure of mighty forces which are alive in his own experience. No doctrine, not one, is for the intellect alone: all go out into heart and conscience and life. More than this: he lets us see that, for Christians, Christ Himself is the great abiding means of grace. He is not only the pledge and guarantee that holiness shall be reached: He is Himself our way of reaching it. He is so for the Christian societies, as well as for the individual Christian soul.
