A ground frequently taken by Christian theologians is that the progress and civilization of the world are due to Christianity; and the discussion is complicated by the fact that many eminent servants of humanity have been nominal Christians, of one or other of the sects. My allegation will be that the special services rendered to human progress by these exceptional men have not been in consequence of their adhesion to Christianity, but in spite of it, and that the specific points of advantage to human kind have been in ratio of their direct opposition to precise Biblical enactments.

There is a court to which I shall appeal: the court of public opinion.

Better a thousandfold abuse of free speech than denial of free speech.

The atheist does not say 'there is no God,' but he says 'I know not what you mean by God; I am without idea of God'; the word 'God' is to me a sound conveying no clear or distinct affirmation. ... The Bible God I deny; the Christian God I disbelieve in; but I am not rash enough to say there is no God as long as you tell me you are unprepared to define God to me.

On the Cross the Jesus of the Four Gospels, who was God, cried out My God, my God, why hast thou forsaken me? God cannot forsake himself, Jesus was God himself. Yet God forsook Jesus, and the latter cried out to know why he was forsaken. Any able divine will explain that of course he knew, and that he was not forsaken. The explanation renders it difficult to believe the dying cry, and the passage becomes one of the mysteries of the holy Christian religion, which, unless a man rightly believe, without doubt he shall perish everlastingly.
