In the languages of mankind, in which everything new is old and everything old is new, an inexhaustible mine has been discovered for researches of this kind. Language still bears the impress of the earliest thoughts of man, obliterated, it may be, buried under new thoughts, yet here and there still recoverable in their sharp original outline. The growth of language is continuous, and by continuing our researches backward from the most modern to the most ancient strata, the very elements and roots of human speech have been reached, and with them the elements and roots of human thought. What lies beyond the beginnings of language, however interesting it may be to the physiologist, does not yet belong to the history of man, in the true and original sense of that word. Man means the thinker, and the first manifestation of thought is speech. But more surprising than the continuity in the growth of language, is the continuity in the growth of religion. Of religion, too, as of language, it may be said that in it everything new is old, and everything old is new, and that there has been no entirely new religion since the beginning of the world. The elements and roots of religion were there, as far back as we can trace the history of man; and the history of religion, like the history of language, shows us throughout a succession of new combinations of the same radical elements. An intuition of God, a sense of human weakness and dependence, a belief in a Divine government of the world, a distinction between good and evil, and a hope of a better life, these are some of the radical elements of all religions. Though sometimes hidden, they rise again and again to the surface. Though frequently distorted, they tend again and again to their perfect form. Unless they had formed part of the original dowry of the human soul, religion itself would have remained an impossibility, and the tongues of angels would have been to human ears but as sounding brass or a tinkling cymbal. If we once understand this clearly, the words of St. Augustine which have seemed startling to many of his admirers, become perfectly clear and intelligible, when he says:[1] 'What is now called the Christian religion, has existed among the ancients, and was not absent from the beginning of the human race, until Christ came in the flesh: from which time the true religion, which existed already, began to be called Christian.' From this point of view the words of Christ too, which startled the Jews, assume their true meaning, when He said to the centurion of Capernaum: 'Many shall come from the east and the west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.' [Footnote 1: August. Retr. 1, 13. 'Res ipsa, quæ nunc religio Christiana nuncupatur, erat apud antiquos, nec defuit ab initio generis humani, quousque Christus veniret in carnem, unde vera religio, quæ jam erat, cœpit appellari Christiana.']
