Now, I am not going to enter upon these matters at any length, but I would just recall to you our Lord's broad, simple principle: 'A corrupt tree cannot bring forth good fruit, neither doth a good tree bring forth evil fruit.' And I would apply that all round. Christian teachers have often made great mistakes, as it seems to me, by tracing the prevalence of the power of some heathen religions to their vices and lies. No system has ever had great moral power in this world but by reason of its excellences and truths. Mohammedanism, for instance, swept away, and rightly, a mere formal superstition which called itself Christianity, because it grasped the one truth: 'There is no God but God'; and it had faith of a sort. Monasticism held the field in Europe, with all its faults, for centuries, because it enshrined the great Christian truth of self-sacrifice and absolute obedience. And you may take it as a fixed rule, that howsoever some 'mixture of falsehood doth ever please,' as Bacon says, in his cynical way, the reason for the power of any great movement has been the truth that was in it and not the lie; and the reason why great men have exercised influence has been their greatness and their goodness, and not their smallnesses and their vices.
I apply that all round, and I ask you to apply it to Christianity; and in the light of such plain principles to answer the question: 'Where did this Man, so fair, so radiant, so human and yet so superhuman, so universal and yet so individual--where did He come from? and where did the Gospel, which flows from Him, and which has done such things in the world as it has done--where did it come from? 'Do men gather grapes of thorns, or figs of thistles?' If it is true that Jesus Christ is either mistakenly represented in the Gospels, or that He made enthusiastic claims which cannot be verified; and if it is true that the faith in a Resurrection on which Christianity is suspended, and which has produced such fruits as we know have been produced, is a delusion; then all I can say is that the noblest lives that ever were lived in the world have found their impulse in a falsehood or a dream; and that the richest clusters that ever have yielded wine for the cup have grown upon a thorn. If like produces like, you cannot account for Christ and Christianity by anything short of the belief in His Divine mission. Serpents' eggs do not hatch out into doves. This Man, when He claimed to be God's Son and the world's Saviour, was no brain-sick enthusiast; and the results show that the Gospel which His followers proclaim rests upon no lie.
