Since the revolt of the Teutonic peoples, the most remarkable phenomenon of Christian history has been the growth of a branch of Teutonic Christianity under the novel political and social conditions of the new world. This has been a transplantation of Christianity quite as significant as any of its transplantations in the past, and the new soil has produced just as unmistakably new a growth. Doubtless none of the great phases of Christianity in the past knew themselves to be new. Neither Greek nor Latin Christianity was conscious of any departure from primitive Christianity. Indeed, to this day, in their conception of the history of the Church, they persist in impressing their own type on that primitive and undeveloped type. Teutonic Christianity took centuries to come to clear consciousness of itself and of its irreconcilability with Latin Christianity. It is not wonderful, therefore, that hitherto, as far as I am aware, American Christianity has been, if at all, very dimly and imperfectly conscious of the difference between its spirit and that of the Teutonic Christianity of the old world. American Christianity has not yet arrived. It is only on the way. It has not yet found itself. It is not yet conscious of its own individuality, not yet self-reliant, independent. It is a youth, but a youth rapidly approaching manhood. Perhaps the characteristics that are unfolding themselves can be most clearly brought out by an attempt to show wherein it resembles, and wherein it differs from, each of the four great phases of Christianity which have just been under consideration. _a_. American Christianity compared with Jewish. Compared with Jewish Christianity, American Christianity resembles the latter in its simplicity of creed, its emphasis on the practical and ethical, and (to a distinct and growing degree) in its brotherliness and democratic equality. But its creedal simplicity is not the same as that of the primitive Jewish Church. That Church was wise in the brevity and simplicity of its creed, but it did not know its own wisdom. American Christianity is wise and knows its wisdom. It will not, like the Jewish Church, allow itself to be seduced into interminable theological controversies and into the superstition of orthodoxy. Seventeen hundred years of bitter wrangling and bloody conflict and cruel persecutions have taught it something. It has a short and a simple creed, not because it knows so little, but because it knows so much.
