The evidence of the historian Tacitus is conclusive upon this point. He lived and flourished all through the time when St. Paul's ministry was most active. He was born about the year 50, and had every opportunity of becoming acquainted with the facts concerning the execution of Christ and the rise of Christianity, as they were doubtless laid up in the imperial archives at Rome. His testimony, written at a period when, as some maintain, neither the Acts of the Apostles nor the Gospels of the New Testament were in existence, exactly tallies with the account given by our sacred books. In his _Annals_, book xv., chap. 44, he writes concerning Christianity: "Christus, from whom the name of Christian has its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilate, and a most mischievous superstition, thus checked for the moment, again broke out in Judæa." So that the Pagan historian, who knew nothing about Christianity save what official pagan documents or popular report told him, agrees with the Scriptures that Christianity was checked for a moment by the death of its founder, and then gained its earliest and most glorious triumph on the very scene of its apparent defeat where--and this is a very important part of the argument--previously the most marvellous wisdom and the most striking signs and wonders had utterly failed to gain any large measure of success. Whence, then, can we explain this fact, or how account for this conscience-stricken cry, "Men and brethren, what shall we do?" unless we assume, what the narrative of our text declares, that the Holy Ghost, in all His convincing and converting power, had been poured out from on high?
