Apostle Paul and the Scriptures. An overview of current research and the price of progress. Among Dezső Kállay's biblical studies, the letters of the apostle Paul appear with special emphasis. Paul’s interpretation of the Scriptures was deeply rooted in the active Scriptural tradition of his era, not isolated in hermeneutical vacuum. The Scriptures represented not just the written text but also its interpretation, thus the Israelites’ faith was likened to both a solid foundation and spiritual sustenance, as they “drank from the spiritual rock” (1 Cor 10:4). This study aims to map the key research trajectories concerning Paul’s citations of the Bible. It begins by addressing fundamental issues within accepted consensuses, then evaluates the current state of research, informed by the six-year efforts of the Paul and Scripture Seminar under the Society of Biblical Literature and its two resultant publications. We may conclude that we know more and less at the same time. While no definitive conclusions have been reached on the initial six questions, the primary research paths and their methodological interconnections have become more discernible.
