Nothing could better illustrate the reality of that new character which Christianity confers than the fact that men can be addressed as Christians. Nothing, either, could better illustrate the confusion of mind that exists in this matter, or the insincerity of much profession, than the fact that so many members of churches would hesitate before taking the liberty so to address a brother. We have all written letters, and on all sorts of occasions; we have addressed men as lawyers, or doctors, or men of business; we have sent or accepted invitations to gatherings where nothing would have astonished us more than the unaffected naming of the name of God; did we ever write to anybody because he was a Christian, and because we were Christians? Of all the relations in which we stand to others, is that which is established by "our common Christianity," by our common life in Jesus Christ, the only one which is so crazy and precarious that it can never be really used for anything? Here we see the Apostle look back from Corinth to Thessalonica, and his one interest in the poor people whom he remembers so affectionately is that they are Christians. The one thing in which he wishes to help them is their Christian life. He does not care much whether they are well or ill off in respect of this world's goods; but he is anxious to supply what is lacking in their faith (iii. 10). How real a thing the Christian life was to him! what a substantial interest, whether in himself or in others, engrossing all his thought, absorbing all his love and devotion. To many of us it is the one topic for silence; to him it was the one theme of thought and speech. He wrote about it, as he spoke about it, as though there were no other interest for man; and letters like those of Thomas Erskine show that still, out of the abundance of the heart, the mouth speaketh. The full soul overflows, unaffected, unforced; Christian fellowship, as soon as Christian life is real, is restored to its true place.
Paul, Silas, and Timothy wish the church of the Thessalonians grace and peace. This is the greeting in all the Apostle's letters; it is not varied except by the addition of "mercy" in the Epistles to Timothy and Titus. In form it seems to combine the salutations current among the Greeks and the Jews (χαίρειν and שָׁלוֹם), but in import it has all the originality of the Christian faith. In the second Epistle it runs, "Grace and peace from God the Father and the Lord Jesus Christ." Grace is the love of God, spontaneous, beautiful, unearned, at work in Jesus Christ for the salvation of sinful men; peace is the effect and fruit in man of the reception of grace. It is easy to narrow unduly the significance of peace; those expositors do so who suppose in this passage a reference to the persecution which the Thessalonian Christians had to bear, and understand the Apostle to wish them deliverance from it. The Apostle has something far more comprehensive in his mind. The peace, which Christ is; the peace with God which we have when we are reconciled to Him by the death of His Son; the soul-health which comes when grace makes our hearts to their very depths right with God, and frightens away care and fear; this "perfect soundness" spiritually is all summed up in the word. It carries in it the fulness of the blessing of Christ. The order of the words is significant; there is no peace without grace; and there is no grace apart from fellowship with God in Christ. The history of the Church has been written by some who practically put Paul in Christ's place; and by others who imagine that the doctrine of the person of Christ only attained by slow degrees, and in the post-apostolic age, its traditional importance; but here, in the oldest extant monument of the Christian faith, and in the very first line of it, the Church is defined as existing in the Lord Jesus Christ; and in that single expression, in which the Son stands side by side with the Father, as the life of all believing souls, we have the final refutation of such perverse thoughts. By the grace of God, incarnate in Jesus Christ, the Christian is what he is; he lives and moves and has his being there; apart from Christ, he is not. Here, then, is our hope. Conscious of our own sins, and of the shortcomings of the Christian community of which we are members, let us have recourse to Him whose grace is sufficient for us. Let us abide in Christ, and in all things grow up into Him. God alone is good; Christ alone is the Pattern and the Inspiration of the Christian character; only in the Father and the Son can the new life and the new fellowship come to their perfection.
