Was Jesus a Liar, Enthusiast or a Madman?

This testimony [that Jesus was God], if not true, must be downright blasphemy or madness. . . . Self-deception in a matter so momentous, and with an intellect in all respects so clear and so sound, is equally out of the question. How could he be an enthusiast or a madman who never lost the even balance of his mind, who sailed serenely over all the troubles and persecutions, as the sun above the clouds, who always returned the wisest answer to tempting questions, who calmly and deliberately predicted his death on the cross, his resurrection on the third day, the outpouring of the Holy Spirit, the founding of his Church, the destruction of Jerusalem—predictions which have been literally fulfilled? A character so original, so complete, so uniformly consistent, so perfect, so human and set so high above all human greatness, can be neither a fraud nor a fiction. The poet, as has been well said, would in this case be greater than the hero. It would take more than a Jesus to invent a Jesus.
