Such being the state of the case, I would ask any impartial reader whether there is any evidence here that these few words, introduced without the slightest indication of the source from which they were derived, must have been quoted from our third Gospel, and cannot have been taken from some one of the numerous evangelical works in circulation before that Gospel was written. The reply of everyone accustomed to weigh evidence must be that the words cannot even prove the existence of our synoptic at the time the letter was written.
"But, if our author disposes of the coincidences with the third Gospel in this way" (proceeds Dr. Lightfoot), "what will he say to those with the Acts? In this same letter of the Gallican Churches we are told that the sufferers prayed for their persecutors 'like Stephen, the perfect martyr, "Lord, lay not this sin to their charge.'" Will he boldly maintain that the writers had before them another Acts, containing words identical with our Acts, just as he supposes them to have had another Gospel, containing words identical with our Third Gospel? Or, will he allow this account to have been taken from Acts vii. 60, with which it coincides? But in this latter case, if they had the second treatise, which bears the name of St. Luke, in their hands, why should they not have had the first also?" [143:1]
"There is no mention of the Acts of the Apostles in the epistle, and the source from which the writers obtained their information about Stephen, is, of course, not stated. If there really was a martyr of the name of Stephen, and if these words were actually spoken by him, the tradition of the fact, and the memory of his noble saying, may well have remained in the Church, or have been recorded in writings then current, from one of which, indeed, eminent critics (as Bleek, Ewald, Meyer, Neander, De Wette) conjecture that the author of Acts derived his materials, and in this case the passage obviously does not prove the use of the Acts. If, on the other hand, there never was such a martyr by whom the words were spoken, and the whole story must be considered an original invention by the author of Acts, then, in that case, and in that case only, the passage does show the use of the Acts. Supposing that the use of Acts be held to be thus indicated, what does this prove? Merely that the 'Acts of the Apostles' were in existence in the year 177-178, when the epistle of Vienne and Lyons was written. No light whatever would thus be thrown upon the question of its authorship; and neither its credibility nor its sufficiency to prove the reality of a cycle of miracles would be in the slightest degree established."
