"Savonarola was not merely the expounder of righteousness. He claimed to be a prophet revealing things which, to use his own words, "are beyond the scope of the knowledge which is natural to any creature." This element would have been a sign of weakness, if it had not been associated with a great personality, bent on noble ends. The severity of his warnings was often so fearful that the preacher himself shrank back from delivering them. On one occasion, he spent the entire night in vigils and prayer that he might be released from the duty of making known a message, but in vain. The sermon, he then went forth to preach, he called a terrific sermon."
