But it was chiefly the two former branches of theology that engaged his attention. In his _Exegetical Explication of Particular Passages_ he accomplished an important service for the church. He introduced all the leading doctrines of inspiration into this work, and discussed the merits of contemporary controversy in connection with them. He explained those almost indefinable terms which had been so variously employed by the schoolmen, and summed up the literature on the points in question. His style was prolix but his conclusions carried great weight with them. As a specimen of his tedious method, he begins his discussion of original sin with the questions, "Is there such a thing as original sin? Then, what is it? What is its subject? How is it continued?" Many other inquiries are made in the same manner, but it is only after a hundred pages have been passed over that he gives his own definition of it. But we should not smile at such latitude of style when we remember the literary standard of those times. The German language was then in its plastic state; and by far the greater portion of writers had been much more interested in gaining points than rounding periods. It is almost a hopeless task to wade through the ridiculously lengthy terms of the seventeenth century. But it may be said, in their defence, that the method of verbose composition was not without some appearance of utility. The intelligence of the reader could not be relied upon to such an extent as now, and the eager eyes of so many opponents made it necessary to guard every word of importance with a wall of sentences. We have now to mention a fourth actor in the great drama of these dangerous times, John Valentine Andreae. His mind was not of the serious tone that marked the other writers of whom we have spoken. That he looked deeply, calmly, and wisely into the surrounding evils no one can doubt. Every work he wrote established this fact. But the method which he adopted to cure them was of a totally different order from that employed by others. His personal history bears all the evidences of romance. He was the son of a poor widow, who, having spent all her property to give him an education, found her boy at the conclusion of his studies desirous of making the usual academic tour. She has but a pittance left, so she puts into his hand twelve kreutzer, and a rusty old coin, as a pocketpiece. Her eyes follow him until they are blinded in a flood of tears. Years pass on and Valentine comes home, having travelled, by dint of self-denial and perseverance, over the most interesting portions of the Continent. He returns to the fatherland and settles quietly down as an orthodox Lutheran pastor.
