1. This unity and peace may consist with the ignorance of many truths, and in the holding of some errors; or else this duty of peace and unity could not be practicable by any on this side perfection: but we must now endeavour the unity of the spirit, till we come to the unity of the faith, and of the knowledge of the Son of God; Eph. iv. 13. Because now, as the apostle saith, “We know in part, and we prophesy in part,” and “Now we see through a glass darkly;” 1 Cor. xiii. 9, 12. And as this is true in general, so we may find it true if we descend to particular instances. The disciples seem to be ignorant of that great truth which they had often, and in much plainness, been taught by their Master once and again, viz., that his kingdom was not of this world, and that in the world they should suffer and be persecuted; yet in the 1st of the Acts, ver. 6, we read, that they asked of him if he would at this time restore the kingdom to Israel? thereby discovering that Christ’s kingdom (as they thought) should consist in his temporal jurisdiction over Israel, which they expected should now commence and take place amongst them. Again, our Lord tells them, that he had many things to say (and these were many important truths) which they could not now bear; John xvi. 12. And that these were important truths, appear by the 10th and 11th verses, where he is discoursing of righteousness and judgment, and then adds, that he had yet many things to say which they could not bear; and thereupon promises the Comforter to lead them into ALL TRUTH; which implies, that they were yet ignorant of many truths, and consequently held divers errors; and yet for all this, he prays for, and presses them to, their great duty of peace and unity; John xiv. 27; xvii. 21. To this may be added that of Heb. v. 11, where the author saith, he had many things to say of the priestly office of Christ, which by reason of their dulness they were not capable to receive; as also that in the 10th of the Acts, where Peter seems to be ignorant of the truth, viz., that the gospel was to be preached to all nations; and contrary hereunto, he erred in thinking it unlawful to preach amongst the Gentiles. I shall add two texts more, one in Acts xix., where we read that those disciples which had been discipled and baptized by John were yet ignorant of the Holy Ghost, and knew not (as the text tells us) whether there were any holy Ghost or no; though John did teach constantly, that he that should come after him should baptize with the Holy Ghost and fire. From hence we may easily and plainly infer, that Christians may be ignorant of many truths, by reason of weak and dull capacities, and other such like impediments, even while those truths are with much plainness delivered to them. Again, we read, Heb. v. 13, of some that were unskilful in the word of righteousness, who nevertheless are called babes in Christ, and with whom unity and peace is to be inviolably kept and maintained.
