16. They are to be censured according to whose representations and views a Christian Church is to be advocated which should be in all respects without infirmity and defect, and who teach that, when perfection is not in evidence, there is no such thing as the Church of Christ nor as true Christians. Many erring spirits, especially strong pretenders to wisdom, and precocious, self-made saints, immediately become impatient at sight of any weakness in Christians who profess the Gospel faith; for their own dreams are of a Church without any imperfections, a thing impossible in this earthly life, even they themselves not being perfect. 17. Such, we must know, is the nature of Christ's office and dominion in his Church that though he really does instantaneously, through faith, confer upon us his purity, and by the Spirit transforms our hearts, yet the work of transformation and purification is not at once completed. Daily Christ works in us and purges us, to the end that we grow in purity daily. This work he carries on in us through the agency of the Word, admonishing, reproving, correcting and strengthening; as in the case of the Corinthians through the instrumentality of Paul. Christ also uses crosses and afflictions in effecting this end. He did not come to toil, to suffer and to die because he expected to find pure and holy people. Purity and holiness for us he has acquired in his own person to perfection, inasmuch as he was without sin and perfectly pure from the moment he became man, and this purity and holiness he communicates to us in their flawless perfection in so far our faith clings to him. But to attain personal purity of such perfection requires a daily effort on the part of Christ, until the time shall have come that he has wrought in us a flawless perfection like his own. So he has given us his Word and his Spirit to aid us in purging out the remaining old leaven, and in holding to our newly-begun purity instead of lapsing from it. We must retain the faith, the Spirit and Christ; and this, as before said, we cannot do if we give place to the old carnal disposition instead of resisting it. 18. Note, one thing the text teaches: Even the saints have weakness, uncleanness and sin yet to be purged out, but it is not imputed unto them because they are in Christ and occupied in purging out the old leaven. 19. Another thing, it teaches what constitutes the difference between the saints and the unholy, for both are sinful; it tells the nature of sins despite the presence of which saints and believers are holy, retaining grace and the Holy Spirit, and also what sins are inconsistent with faith and grace.
