An NLP based AI tool was developed for topic mining Christian writings of major figures from different Christian eras and movements. The text corpus chosen for text mining includes : the volumes of Augustine and John Chrysostom from the patristic period, the writings of Thomas Aquinas from the Scholastic period, the writings of John Calvin the reformer and the text corpus of sermons by George Whitefield and John Wesley that mark the beginning of the modern Christian evangelical movement and evangelicalism. The topics text mined and topics summarized include : Gospel, Salvation, Jesus Christ, Sin, Temptation, Tribulation, Pride, Lust, Envy, Joy, Hope, Charity, Marriage, Church, Heaven, Hell. They are downloadable from the link - https://drive.google.com/drive/folders/1tG2Y36MF1ApvYnhPM_njtNvKYiv7_8RL?usp=sharing and this is expected to help Christian content developers. The link to the code of the NLP tool hosted in the GitHub repository is provided to aid further development - https://github.com/bengeof/AI-driven-Theology-Open-Development. These tools must not be viewed as threatening the role of the human in humanities research broadly and specifically in Christian theology but as empowering the human with additional powers of AI for research in the humanities in the age of Big Data.
