Shortly after Robert L. Lindsey’s eureka moment (“Luke is first!”) on February 14, 1962, and at Professor David Flusser’s urging, Lindsey submitted the following article to the editors of Novum Testamentum. The article was published in the journal’s November 1963 issue as “A Modified Two-Document Theory of the Synoptic Dependence and Interdependence,” Novum Testamentum, Vol. 6, Fasc. 4 (November 1963): 239-263. Lauren S. Asperschlager, David N. Bivin and Joshua N. Tilton have updated and emended the article to bring it in line with the modifications Lindsey made to his hypothesis over the following 30 years. Pieter Lechner has created the tables and graphics.
