I’ve been enjoying reading Jürgen Moltmann’s The Trinity and the Kingdom of God (London: SCM, 1981), which I’ve posted a few quotes from recently. One of Moltmann’s main aims in this book is to argue for a more “social” conception of the Trinity, one which starts from the three Persons — Father, Son, and Spirit — as we encounter them in Scripture, and moves to their unity from that starting point. In consequence, Moltmann suggests, we must understand the unity of the Trinity not as a unity of substance or subjectivity, but of fellowship. Here are some highlights:
… the unity of the Trinity cannot be a monadic unity. The unity of the divine tri-unity lies in the union of the Father, the Son, and the Spirit, not in their numerical unity. It lies in their fellowship, not in the identity of a single subject. (p.95)
Strict monotheism has to be theocratically conceived and implemented, as Islam proves. But once it is introduced into the doctrine and worship of the Christian church, faith in Christ is threatened: Christ must either recede into the series of the prophets, giving way to the One God, or he must disappear into the One God as one of his manifestations. (p.131)
If we search for a concept of unity corresponding to the biblical testimony of the triune God, the God who unites others with himself, then we must dispense with both the concept of the one substance and the concept of the identical subject. All that remains is: the unitedness, the at-oneness of the three Persons with one another, or: the unitedness, the at-oneness of the triune God. For the concept of unitedness is the concept of a unity that can be communicated and is open… If the unity of God is not perceived in the at-oneness of the triune God, and therefore as a perichoretic unity, then Arianism and Sabellianism remain inescapable threats to Christian theology. (p.150)
