The author of Second Thessalonians, whose epistle is a self-evident forgery, declares First Thessalonians to be a forgery. Baur and the Tubingen school reject both Epistles. Baur also rejects Philippians: "The Epistles to the Colossians and to the Philippians ... are spurious, and were written by the Catholic school near the end of the second century, to heal the strife between the Jew and the Gentile factions" (Paulus). Dr. Kuenen and the other Dutch critics admit that Philippians and Philemon, as well as First Thessalonians, are doubtful. That the Pastoral Epistles are forgeries is now conceded by all critics. According to the German critics they belong to the second century. Hebrews does not purport to be a Pauline document. Luther says: "The Epistle to the Hebrews is not by St. Paul, nor, indeed, by any apostle" (Standing Preface to Luther's N. T.). Four Epistles--Romans, First and Second Corinthians, and Galatians--while rejected by a few critics, are generally admitted to be the genuine writings of Paul. These books were written, it is claimed, about a quarter of a century after the death of Christ. They are the only books of the New Testament whose authenticity can be maintained. Admitting the authenticity of these books, however, is not admitting the historical existence of Christ and the divine origin of Christianity. Paul was not a witness of the alleged events upon which Christianity rests. He did not become a convert to Christianity until many years after the death of Christ. He did not see Christ (save in a vision); he did not listen to his teachings; he did not learn from his disciples. "The Gospel which was preached of me is not after man, for I neither received it of man, neither was I taught it" (Gal. i, 11, 12). Paul accepted only to a very small extent the religion of Christ's disciples. He professed to derive his knowledge from supernatural sources--from trances and visions. Regarding the value of such testimony the author of "Supernatural Religion" (p. 970) says: "No one can deny, and medical and psychological annals prove, that many men have been subject to visions and hallucinations which have never been seriously attributed to supernatural causes. There is not one single valid reason removing the ecstatic visions and trances of the Apostle Paul from this class." The corporeal existence of the Christ of the Evangelists receives slight confirmation in the writings of Paul. His Christ was not the incarnate Word of John, nor the demi-god of Matthew and Luke. Of the immaculate conception of Jesus he knew nothing. To him Christ was the son of God in a spiritual rather than in a physical sense. "His son Jesus Christ our Lord, which was made of the seed of David according to the flesh; and declared to be the son of God with power, according to the spirit of holiness, by the resurrection from the dead" (Rom. i, 3, 4). "God sent forth his son, made of a woman [but not of a virgin], made under the law" (Gal. iv, 4).
