In order to recover the Korean church, which has experienced rapid changes in circumstances and stagnation during COVID-19, preaching must be restored as per the principle that the more urgent the situation, the more basics must be returned to. However, since it is impossible for preachers to identify their own weaknesses and development factors on their own, a sermon critique group is needed where preachers can gather regularly and demonstrate collective intelligence. In order to criticize a sermon, you must have a certain level of preaching philosophy and set a standard for evaluating the sermon, and that standard is validity and relevancy. This is because the two pillars of sermon are interpretation and delivery. Interpretation requires validity based on correct interpretation of the Bible, and delivery requires relevancy based on the needs of the audience. There is a triple-perspective biblical interpretation methodology advocated by Stuart and Fee for a legitimate biblical interpretation. The tripleperspective biblical interpretation methodology involves historical interpretation, literary interpretation, and theological interpretation of the text. Another biblical interpretation methodology is Seungjin Lee’s “Bible interpretation methodology from the perspective of homiletical intertextuality,” which is based on the reader’s context in the text and the pre-text used by the author to solve the reader’s problems. The view is that it contains the post-text intended by the author. Preachers who interpret the Bible from an intertextuality perspective must also write sermons from an intertextuality perspective, which is in line with the intersection model of preaching.
