'... ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren.'--1 Peter i. 22.
Note these three subsidiary clauses introduced respectively by 'in,' 'through,' 'unto.' They give the means, the Bestower, and the issue of the purity of soul. The Revised Version, following good authorities, omits the clause, 'through the Spirit.' It may possibly be originally a marginal gloss of some scribe who was nervous about Peter's orthodoxy, which finally found its way into the text. But I think we shall be inclined to retain it if we notice that, throughout this epistle, the writer is fond of sentences on the model of the present one, and of surrounding a principal clause with subsidiary ones introduced by a similar sequence of prepositions. For instance, in this very chapter, to pass over other examples, we read, 'Kept by' (or in) 'the power of God through faith unto salvation.' So, for my present purpose, I take the doubtful words as part of the original text. They unquestionably convey a true idea, whether they are genuine here or no.
One more introductory remark--'Ye have purified your souls'--a bold statement to make about the vast multitude of the 'dispersed' throughout all the provinces of Asia Minor whom the Apostle was addressing. The form of the words in the original shows that this purifying is a process which began at some definite point in the past and is being continued throughout all the time of Christian life. The hall-mark of all Christians is a relative purity, not of actions, but of soul. They will vary, one from another; the conception of what is purity of soul will change and grow, but, if a man is a Christian, there was a moment in his past at which he potentially, and in ideal, purified his spirit, and that was the moment when he bowed down in obedience to the truth. There are suggestions for volumes about the true conception of soul-purity in these words of my text. But I deal with them in the simplest possible fashion, following the guidance of these significant little words which introduce the subordinate clauses.
First of all, then, we have here the great thought that
I. Soul purity is in, or by, obedience.
Now, of course, 'the truth'--truth with the definite article--is the sum of the contents of the Revelation of God in Jesus Christ, His life, His death, His Glory. For to Peter, as to us He should be, Jesus Christ was Truth Incarnate. 'In Him were hid all the treasures of wisdom and knowledge.' The first thought that is suggested to me from this expression--obedience to the truth--is that the revelation of God in Jesus Christ is, as its ultimate intention, meant to be obeyed. There are plenty of truths which have no influence on life and conduct, for which all is done that they can demand when they are accepted. But _the_ truth is no inert substance like the element which recent chemical discoveries have found, which is named 'argon,' the do-nothing: _the_ truth is, as physiologists say, a ferment. It is intended to come into life, and into character, and into the inmost spirit of a man, and grip them, and mould them, and transform them, and animate them, and impel them. The truth is to be 'obeyed.'
Now that altogether throws over two card-castles which imperfect Christians are very apt to build. One which haunted the thoughts of an earlier generation of Christians more than it does the present, is that we have done all that 'the truth' asks of us when we have intellectually endorsed it. And so you get churches which build their membership upon acceptance of a creed and excommunicate heretics, whilst they keep do-nothing and uncleansed Christians within their pale. But God does not tell us anything that we may know. He tells us in order that, knowing, we may be and do. And right actions, or rather a character which produces such, is the last aim of all knowledge, and especially of all moral and religious truth. So 'the truth' is not 'argon', it is a ferment. And if men, steeped to the eyebrows in orthodoxy, think that they have done enough when they have set their hands to a confession of faith, and that they are Christians because they can say, 'all this I steadfastly believe,' they need to remember that religious truth which does not mould and transform character and conduct is a king dethroned; and for dethroned kings there is a short step between the throne from which they have descended and the scaffold on which they die.
