"When thou art converted, strengthen thy brethren" (Luke xxii. 32), was the Lord's injunction to St. Peter, of which this Epistle may be considered as a part fulfilment. So richly stored is it with counsel, warning, and consolation that Luther, the conflicts of whose life will bear some comparison with the trials of these Asian converts, calls it one of the most precious portions of the New Testament Scriptures. Its value is further enhanced because in so many places the Apostle reverts in thought or word to his own life-history, and draws his teaching from the rich stream of personal experience. Even the name which he sets at the head of the letter had its lesson in connexion with Jesus. Most Jews took a second name for profaner use in their commerce with the heathen; but to Simon, the son of Jonas, Peter must have been a specially sacred name, must have served as a watchword both to himself and to all others who had learnt the story of its bestowal and the meaning which was bound up with it. That a letter by St. Peter should be, as this is, of a very practical character is no more than we might expect from what we know of the Apostle from the Gospels. Prompt in word and action, ever the spokesman of the twelve, he seems made for a guide and leader of men. What perhaps we should not have expected is the very definite doctrinal language with which the Epistle opens. Nowhere in the writings either of St. Paul or St. John do we find more full or more instructive teaching concerning the Holy Trinity. And herein St. Peter has been guided to choose the only order which tends to edification. Sound lessons for Christian life must be grounded upon a right faith, and a brother can afford no strength to his brethren unless first of all he point them clearly to the source whence both his strength and theirs must come. Of the previous intercourse between St. Peter and those to whom he writes we can only judge from the Epistle itself. The Apostle's name disappears from New Testament history after the Council of Jerusalem (Acts xv.), but we feel sure his labours did not cease then; and though the first message of Christianity may have been brought to these Asiatic provinces by St. Paul, the allusions which St. Peter makes to the trials of the converts are such as seem impossible had he not himself laboured among them. The frequent reminders, the special warnings, could come only from one who knew their circumstances very intimately. Allusions to the former lusts indulged in in their days of ignorance, to the reproaches which they now have to suffer from their heathen neighbours, to their going astray like lost sheep, are a few of the unmistakable evidences of personal knowledge.
