“Even of old the Christian world, so bitterly antagonistic to any ideas not specifically contained in their creeds and dogmas, made an exception in Socrates’ case. They recognized his likeness to Christ. He was the example that a soul could be Christlike, not through grace, but by nature. Erasmus said: "Holy Socrates, pray for us." To know him is a help to knowing Christ, and it is not hard to know him. We can see him quite clearly. Plato, who drew his portrait, could not, of course, keep himself out of it, any more than Christ’s recorders could; but at least magic did not dog Plato’s footsteps, as it did everyone’s footsteps when the Gospels were written. In the fourth century B. C. Greeks had no leaning to marvels. Also in the centuries that followed no one founded a church on Socrates and built up around him a theology and hung creeds and ceremonials upon him. To see what he was, we do not have to brush anything away, except a bit of Plato. We can use him as a stepping stone to Christ, a first aid in realizing what Christ was.”
