Or, look at the matter numerically. Jesus, who avowedly confined his missionary efforts to his own race, "for to them only am I sent," is made by the writer of Matthew's Gospel to give a world-wide commission to his disciples on the very eve of his mysterious disappearance from earth: "Go ye and teach all nations," he is reported to have enjoined upon them. Peter, doubtless, was present upon this occasion, or, at any rate, we cannot conceive him ignorant of the commission; and yet we find him refusing point-blank to admit Cornelius the centurion--the first candidate who offered himself--into the Church, and, according to the Acts, a sheet full of animals had to be let through the roof of his house before he could be turned from his purpose of confining the new religion exclusively to Jews. The explanation, of course, of such universality as Christianity has attained is mainly due to the influence of the cosmopolitan Saul of Tarsus, though the idea of an Oecumenical Society was by no means his original thought. The Stoics were full of the ideal, and the Cynics before them, while Socrates refused to describe himself as a citizen of Athens, but claimed the whole world as his fatherland, and the outer barbarians, as the exclusive Greeks styled them, he called his brethren. And, now, how many of the human family are enrolled as "citizens of the holy places"; what numbers assemble for worship in the great cathedral? Statistics are unnecessary, but we cannot but remember the temples to God raised in other ages and other lands, which endure to this hour, imperishable witnesses to a truth which is "the light of life". What that truth is, we shall see later. But when we remember the great pre-Christian systems of the East and of Egypt, and the very stones dug out of the earth cry aloud in witness to the eternal truths, God, Soul, Hereafter; when we realise the devotion of martyred Israel to the faith of their fathers, and the great Mohammedan revolt against the dogmatical puerilities of the sixth century; when, I say, we remember that one and all endure to this hour, and in unimpaired vigour, and still more, when that absorbingly interesting study known as the science of Comparative Religion has shown us that of orthodoxy is true what is true of all religious systems--that it enjoys a monopoly of nothing save of errors peculiar to itself, and that of its doctrines, all that is true is not new, and all that is new is not true--we are in a fairer position to estimate its precise place and influence in the world and the sources from which it has drawn its inspiration.
