3.5 stars. In recent years, the retrieval and recovery of the doctrine of union with Christ as the architectonic piece of soteriology has gained traction, specifically in Pauline theology and especially within Reformed scholarship but also outside of it. Dr Bowsher does the church an excellent service by embarking on the theological study of union with Christ within the Johannine corpus, which has been somewhat neglected as compared to its Pauline counterpart.
Firstly, Bowsher does an excellent job of setting the scene by drawing on the pertinent theological works that are relevant to the Johaninnie union: Constantine Campbell's extensive exegetical work on Pauline union (read this a couple of years back); Richard Buackham's thematic study on John's Gospel; Grant Macaskill's work on the theological and exegetical study of union with Christ within the New Testament as a whole; Michael Gorman's work on participation with Christ in John's Gospel; Pascal-Marie Jerumanis' eternal life in John's Gospel as participation in Christ, and so on.
Following this, the bulk of Bowsher's work goes into the exegetical exploration of passages such as John 6, 13-17, and the Johannine epistles. He first works on the Johannine Gospel and Epistles interdependently, before bringing them together for theological synthesis. Two theological themes emerged as the twin motif of Johannine union: participation in the life of Christ as eternal-eschatological life that is coextensive with faith in Christ, being born of the Spirit and fellowship within the Father-Son relationship; and participation in the journey of Jesus, that is, in Jesus' sending, living, rejection by the world, suffering, resurrection and mission. Here Bowsher draws parallels with the positional (justification) and transformational (sanctification) aspects that are found often within Pauline soteriology and binds them together by concluding that the Johannine union is ultimately relational (being born of God and therefore living in relation to God). Hence, Bowsher posits that "participation" is a better nomenclature for the Johannine union, because as Pauline union often denotes "one-ness," participation within the Johannine corpus seems to suggest "in-one-anotherness, and therefore Johannine participation is characterized by the loving relational intimacy between the children of God and the Father-Son fellowship. After that, Bowsher also attempted to synthesise his study of Johannine's participation with the historic dogmas of theosis (eastern orthodoxy), filiation (doctrine of adoption) and covenant theology. I have personally found Bowsher's synthesis of Johannine's participation with covenant theology really fruitful, citing Michael Horton "union with Christ and the covenant of grace are not simply related themes, but are different ways of talking about one and the same reality." Both covenant theology in the OT and Johannine's participation culminate and climax in the goal of eschatological life. Additionally, the Reformed tradition has conceived of Pauline union with Christ as threefold: predestinarian, redemptive-historical, and existential. Bowsher's study on Johannine's participation which yields both positional and transformation aspects seem to correlate and overlap, though not entirely, with the redemptive-historical (participation with Jesus' journey) and existential aspects (participation in eschatological life). David Garner's work on adoption as the architectonic piece of Pauline soteriology seems to correlate perfectly with Bowsher's conclusion that Johannine's participation is ultimately relational: it is that "in-one-anotherness," loving intimacy that binds the children of God in fellowship and participation with the Father and the Son.
Bowsher's study on Johannine's participation is definitely a great contribution to New Testament soteriology as a whole. Minimally, it revealed greater canon unity between John and Paul, between the Gospels and the Epistles and postulate a more profound, intricate and unified theological motif of NT soteriology that is centred upon participation and union with Christ. Bowsher's exegetical work is sublime, and I have especially enjoyed how Bowsher, building on other Johannine scholars, delineates the Christian participation in Jesus' journey through the entire Gospel. However, I find some of his theological synthesis lacking or somewhat underwhelming (I can only give this book a 3.5 stars/5 top). Firstly, even though Bowsher attempts to synthesise Johannine's participation with theosis and filiation, his theological workings are lacking. On theosis, there were barely two pages to delineate what theosis exactly is, and how the multifaceted works of the Greek Fathers conceived of this historic dogma; on filiation, Bowsher mentions the doctrine of adoption in passing, but theologians (such as Tim Trumper) has often pointed out and debated the relationship between filiation in Johannine corpus and filiation in Pauline, and delineated "being born of God" in Johannine as "regeneration" and not "adoption," which is found in Paul. Bowsher skipped over this issue entirely and assumed filiation in both John and Paul as synonymous (I think the word "regeneration" is never mentioned at all!). Thirdly, there is only a light attempt to define and translate "monegenes" within this study, and I am left wondering how Bowsher relates children of God as being begotten by God and Jesus' unique eternal generation, and I am cautious to make this relationship symmetrical without first making exegetical and theological distinctions. Finally, on a point of writing style that also contributes to the theological synthesis, Bowsher seems to belabour his points a fair bit and repetitively restates his conclusions, and I also find the distinction between "oneness" and "in-one-anotherness" unnecessarily repetitious, and at most, confusing, because he seems to use "union" and "participation" sometimes interchangeably, and other times use one term to define or clarify the another. It would have been helpful if Bowsher had stated his definition of participation vs union upfront, and committed to the theological shorthand rather than excessively distinct between "in-one-anotherness" and "oneness" across this book. Overall, a really good contribution of exegetical work to Johannine studies and NT theology-soteriology, but many areas could be strengthened.
