In recent years, there has been a growing body of literature examining the concept of “union with Christ” in Pauline texts, offering various proposals and interpretations aimed at providing a coherent explanation of this concept within Paul's epistles. This article critically evaluates three recent works that attempt to explicate Paul’s notion of “participation in Christ”: Blackwell's Christosis, Gorman’s Inhabiting the Cruciform God, and Macaskill’s Union with Christ in the New Testament. The evaluation is conducted based on the following criteria: theosis, the definition of participation in Christ, the distinction between Creator and creation, and the thematic centrality of participation in Christ within Paul’s thought. Finally, this study explores whether the theme of participation in Christ occupies a central position in Pauline theology and suggests potential avenues for further research, particularly regarding the relationship between sacraments, rituals, and the theme of participation in Christ.
