RT Article T1 Participation “In the Heavenlies” in Christ: Deification in Ephesians JF Religions VO 14 IS 6 A1 Kim, Kangil LA English PB MDPI YR 2023 UL https://ixtheo.de/Record/1848926057 AB Paul’s expression “in the heavenlies” provides an intriguing showcase of the power dynamics of the divine–human relationship (e.g., 1:3, 20; 2:6; 3:10; 6:12). While scholars have identified the theme of union with Christ as an interpretive key for understanding believers’ position in the heavenlies, few have provided adequate attention to “in the heavenlies” according to the significance of theosis. I argue that a patristic idea of theosis offers an interpretive lens in understanding believers’ lives in the heavenlies. Thus, this study aims to situate the discussion on the heavenlies vis-à-vis the conversation around theosis in the New Testament.
