Union with Christ in the New Testament

Union with Christ in the New Testament is a study of the union between God and those he has redeemed, as it is represented in the New Testament. In conversation with historical and systematic theology, Grant Macaskill argues that the union between God and his people is consistently represented by the New Testament authors as covenantal, with the participation of believers in the life of God specifically mediated by Jesus, the covenant Messiah: hence, it involves union with Christ. Christ's mediation of divine participation of believers in the life of God specifically mediated by Jesus, the covenant Messiah: hence, it involves union with Christ. Christ's mediation of divine presence is grounded in the ontology of the Incarnation, the real divinity and real humanity of his person, and by the full divine personhood of the Holy Spirit, who unites believers to him in faith. His personal narrative of death and resurrection is understood in relation to the covenant by which God's dealings with humanity are ordered. In their union with him, believers are transformed both morally and noetically, so that the union has an epistemic dimension, strongly affirmed by the theological tradition but sometimes confused by scholars with Platonism. This account is developed in close engagement with the New Testament texts, read against Jewish backgrounds, and allowed to inform one another as context. As a 'participatory' understanding of New Testament soteriology, it is advanced in distinction to other participatory approaches that are here considered to be deficient, particularly the so-called 'apocalyptic' approach that is popular in Pauline scholarship, and those attempts to read New Testament soteriology in terms of theosis, elements of which are nevertheless affirmed.

Grant Macaskill is the Kirby Laing Chair of New Testament Exegesis at the University of Aberdeen. Prior to this, he had taught as Senior Lecturer in New Testament at the University of St Andrews. His research engages with the New Testament as a coherent body of theological literature emerging from the diverse contexts of late Second Temple Judaism. His publications include In the Fullness of Time: Essays on Christology, Creation, and Eschatology in Honor of Richard Bauckham (2016), The Slavonic Texts of 2 Enoch (2013), and Revealed Wisdom and Inaugurated Eschatology in Ancient Judaism and Early Christianity (2007).
