“Prophet,” he said, presumably addressing Kalon, “I wish you would tell me a lot about your religion.”

“I shall be proud to do it,” said Kalon, inclining his still crowned head, “but I am not sure that I understand.”

“Why, it’s like this,” said Father Brown, in his frankly doubtful way:  “We are taught that if a man has really bad first principles, that must be partly his fault.  But, for all that, we can make some difference between a man who insults his quite clear conscience and a man with a conscience more or less clouded with sophistries.  Now, do you really think that murder is wrong at all?”

“Is this an accusation?” asked Kalon very quietly.

“No,” answered Brown, equally gently, “it is the speech for the defence.”

In the long and startled stillness of the room the prophet of Apollo slowly rose; and really it was like the rising of the sun.  He filled that room with his light and life in such a manner that a man felt he could as easily have filled Salisbury Plain.  His robed form seemed to hang the whole room with classic draperies; his epic gesture seemed to extend it into grander perspectives, till the little black figure of the modern cleric seemed to be a fault and an intrusion, a round, black blot upon some splendour of Hellas.

“We meet at last, Caiaphas,” said the prophet.  “Your church and mine are the only realities on this earth.  I adore the sun, and you the darkening of the sun; you are the priest of the dying and I of the living God.  Your present work of suspicion and slander is worthy of your coat and creed.  All your church is but a black police; you are only spies and detectives seeking to tear from men confessions of guilt, whether by treachery or torture.  You would convict men of crime, I would convict them of innocence.  You would convince them of sin, I would convince them of virtue.

“Reader of the books of evil, one more word before I blow away your baseless nightmares for ever.  Not even faintly could you understand how little I care whether you can convict me or no.  The things you call disgrace and horrible hanging are to me no more than an ogre in a child’s toy-book to a man once grown up.  You said you were offering the speech for the defence.  I care so little for the cloudland of this life that I will offer you the speech for the prosecution.  There is but one thing that can be said against me in this matter, and I will say it myself.  The woman that is dead was my love and my bride; not after such manner as your tin chapels call lawful, but by a law purer and sterner than you will ever understand.  She and I walked another world from yours, and trod palaces of crystal while you were plodding through tunnels and corridors of brick.  Well, I know that policemen, theological and otherwise, always fancy that where there has been love there must soon be hatred; so there you have the first point made for the prosecution.
