To make accurate and effective biblical sermons, it is crucial to establish a connection between the biblical text and the modern audience. Although the terminology may vary, this process is generally understood as the harmonization of principilization and contextualization, which involves finding the intended meaning of the author and applying its relevance to the contemporary audience. This paper focuses on the theological process that includes principilization and contextualization to appropriately connect the past text with the modern audience, with particular emphasis on the harmony and integration of textuality and canonicity and their influence on the sermon-writing process. To accomplish this, the paper first examines the meaning of textuality and canonicity as integral aspects of God’s comprehensive communicative act, and then sequentially traces the developmental discussions of significant hermeneutical and homiletical models concerning the two facets of principilization and contextualization in the theological process. While acknowledging the necessity of principilization and contextualization based on the meaning-significance model in this theological process, it highlights the importance of integrating textuality and canonicity from the perspective of their unity as part of God’s communicative act. Finally, it presents the homiletical implications of the theological process with a focus on the integration of textuality and canonicity.
