During the second and third missionary journeys, the agitation of the Judaizers, as has already been observed, seems to have subsided. In Corinth, indeed, according to 1 and 2 Corinthians, Paul appears in deadly conflict with certain men who sought to undermine his apostolic authority. Baur made much of this conflict; indeed, he based his reconstruction of apostolic history upon the Corinthian Epistles almost as much as upon Galatians. The starting-point of his investigation was found in the party watchwords mentioned in 1 Cor. i. 12, "I am of Paul; and I of Apollos; and I of Cephas; and I of Christ." The "Christ-party" of the verse, identified with the opponents attacked in 2 Cor. x-xiii, Baur believed to have been an extreme Judaizing party. This extreme Judaizing party, Baur maintained, appealed with some show of reason to the original apostles in Jerusalem. Thus the Corinthian Epistles like the Epistle to the Galatians were made to establish what was to Baur the fundamental fact of apostolic history, a serious conflict of principle between Paul and the original apostles.[64] [64] Baur, "Die Christuspartei in der korinthischen Gemeinde," in _Tübinger Zeitschrift für Theologie_, 1831, 4 Heft, pp. 61-206. Subsequent investigation, however, has cast at least serious doubt upon the Tübingen exegesis, even where it has not discredited it altogether. The whole matter of the Christ-party of 1 Cor. i. 12 is felt to be exceedingly obscure, so obscure that J. Weiss, for example, in his recent commentary on 1 Corinthians, has felt constrained to cut the Gordian knot by regarding the words, "And I of Christ", as an interpolation.[65] Where this heroic measure has not been resorted to, various interpretations have been proposed. Sometimes, for example, the Christ-party has been thought to have consisted of those who rejected the other watchwords, but in such a proud and quarrelsome way that the watchword, "I am of Christ," which should have belonged to all, became only the shibboleth of another party. Sometimes, again, the Christ-party has been regarded as a gnosticizing party which boasted of direct communications with the risen Christ. At any rate, it is very difficult to find in the words "I am of Christ" any clear designation of Judaizers who appealed against Paul to James or to their own connections with Jesus in Palestine. On the contrary, the reader of the first four chapters of 1 Corinthians may well be doubtful whether there were any distinct parties at all. It looks rather as though what Paul was rebuking were merely a spirit of division, which manifested itself now in one watchword and now in another. The Corinthian Christians seem to have been "sermon-tasters"; they were proud of their "wisdom," and laid undue stress upon the varying form of the gospel message to the neglect of the content. It is noteworthy that in 1 Cor. i-iv Paul does not enter upon any anti-Judaistic
