§ 42. An unhappy change occurred after Dr. Muhlenberg’s day. The Symbolical Books, which he and his contemporaries received, believed, and sustained in their whole extent, with religious veneration, existed at that time only in Latin and German. They gradually receded from the view of many pastors of the church; individuals were received into the ranks of the ministry, who had never studied them; doctrines and usages, hitherto unknown to the church, were introduced into many Lutheran congregations. At one period several of the most intelligent pastors yielded, to a certain extent, to rationalistic influences; then, the opposite extreme, of fanaticism, gained adherents; both rationalism and fanaticism were alike hostile to “the unaltered Augsburg Confession and the other Symbolical Books,” and a strange combination of elements, derived partly from rationalism, and partly from fanaticism, temporarily held sway. Dependence was now placed on human measures and inventions, designed for the conversion of sinners and the edification of believers, rather than on the divinely appointed means of grace, which men like Arndt and Muhlenberg recognized as the only channels through which the Divine Spirit exercises his influence. If they had lived among us during the second, third, and fourth decades of this century, when their doctrines, and their mode of preaching, were regarded by many as antiquated, or unsuited to a supposed higher grade of religious development, they would have readily predicted the results—fanaticism, latitudinarianism in doctrine, an evanescent emotional religion, and, by consequence, the rejection, in whole or in part, of the Augsburg Confession and the other Symbolical Books. § 43. God, in his mercy, has interposed. The doctrines which Arndt, Muhlenberg, and men of the old faith, regarded as the life-blood of a healthy, scriptural religion, are regaining their authority. Many still reject them; the old faith of the church—Bible truth, is unwelcome to an ignorant, rationalistic, and unconverted heart. But others have been taught by observation and experience that mere human measures and inventions cannot conduct to a healthy and permanent religion, and that divine truth, as taught in the Scriptures, and set forth in our Symbolical Books, and the other means of grace given to the Church by its divine Head, are the only sources from which such a healthy religion can proceed. In this spirit Arndt wrote the “True Christianity,” and by this spirit the Synod of Pennsylvania is animated. This ecclesiastical body desires to take away all glory from man, and to give it all to Christ. One of the results of its attachment to our ancient and holy faith, is the publication of the present volume, in which the author so eloquently and affectionately urges all men to repent, to believe in Christ, and to lead a holy life.
