Understanding union with Christ as a frame of thought (as a motif or theme) is important for accessing Calvin's theology. While the union-with-Christ doctrine arises when Calvin explains the doctrine itself directly (especially in light of soteriology), the strong presence of this motif--union with Christ (union with the Triune God)--indicates its pervasiveness when other doctrines or theological themes are explained as well. This book suggests that we approach the notion of union of Christ as a theological frame of thought that touches on most of the doctrines and theological themes of Calvin's theology. This book deals with union with Christ as a motif or theme rather than as a doctrine.
