What we call Christianity embraces several fundamental doctrines, but the most important of them all is the recognition of the Divine in man, or, as we call it, the belief in the Divinity of the Son. The belief in God, let us say in God the Father, or the Creator and Ruler of the world, had been elaborated by the Jews, and most of the civilised and uncivilised nations of the world had arrived at it. But when the Founder of Christianity called God His Father, and not only His Father, but the Father of all mankind, He did no longer speak the language of either Jews or Greeks. To the Jews, to claim Divine sonship for man would have been blasphemy. To the Greeks, Divine sonship would have meant no more than a miraculous, a mythological event. Christ spoke a new language, a language liable, no doubt, to be misunderstood, as all language is; but a language which to those who understood it has imparted a new glory to the face of the whole world. It is well known how this event, the discovery of the Divine in man, which involves a complete change in the spiritual condition of mankind, and marks the great turning-point in the history of the world, has been surrounded by a legendary halo, has been obscured, has been changed into mere mythology, so that its real meaning has often been quite forgotten, and has to be discovered again by honest and fearless seeking. Christ had to speak the language of His time, but He gave a new meaning to it, and yet that language has often retained its old discarded meaning in the minds of His earliest, nay sometimes of His latest disciples also. The Divine sonship of which He speaks was not blasphemy as the Jews thought, nor mythology as so many of His own followers imagined, and still imagine. Father and Son, divine and human, were like the old bottles that could hardly hold the new wine; and yet how often have the old broken bottles been preferred to the new wine that was to give new life to the world. _Gifford Lectures, III._ If we have learnt to look upon Christianity, not as something unreal and unhistorical, but as an integral part of history, of the historical growth of the human race, we can see how all the searchings after the Divine or Infinite in man were fulfilled in the simple utterances of Christ. His preaching, we are told, brought life and immortality to light. Life, the life of the soul, and immortality, the immortality of the soul, were there and had always been there. But they were brought to light, man was made fully conscious of them, man remembered his royal birth, when the word had been spoken by Christ. _Gifford Lectures, III._
