From the article "Evidence for the Resurrection" by Josh McDowell.
Professor Thomas Arnold, for 14 years a headmaster of Rugby, author of the famous, History of Rome, and appointed to the chair of modern history at Oxford, was well acquainted with the value of evidence in determining historical facts. This great scholar said:
"I have been used for many years to study the histories of other times, and to examine and weigh the evidence of those who have written about them, and I know of no one fact in the history of mankind which is proved by better and fuller evidence of every sort, to the understanding of a fair inquirer, than the great sign which God hath given us that Christ died and rose again from the dead."
Brooke Foss Westcott, an English scholar, said:
"raking all the evidence together, it is not too much to say that there is no historic incident better or more variously supported than the resurrection of Christ. Nothing but the antecedent assumption that it must be false could have suggested the idea of deficiency in the proof of it."
Clark Pinnock Mcmaster University, said:
There exists no document from the ancient world, witnessed by so excellent a set of textual and historical testimonies . . . Skepticism regarding the historical credentials of Christianity is based upon an irrational bias.
E. M. Blaiklock Professor of Classics Auckland University, said:
I claim to be an historian. My approach to Classics is historical. And I tell you that the evidence for the life, the death, and the resurrection of Christ is better authenticated than most of the facts of ancient history . . .
