First, some background. Part of the work of renewing Anglicanism in parishes is finding through-lines in our tradition. Our theological tradition is, of course, nothing to sneeze at (if you are unclear on that point, I invite you to click on the map at right, and of course give serious study to Martin Thornton’s English Spirituality). But perhaps as a place to start, and as an ongoing point of departure, we could say that the axis of our tradition is understood in its simplest form through five theologians: Augustine, Benedict, Anselm, Julian, and Macquarrie. These are the non-negotiables, you might say. They are not optional for Anglicanism. Thus you might call them our “core theologians”.
I mean this term lightly but I do mean it. Through their works, the main contours of the Anglican school of theology/spirituality show up, although of course are not exhausted. These five, within our liturgical life via the BCP, are the bare minimum to get a working sense of the whole tradition, enough to be a solid point of departure toward the study of any theologian one wants to study.
Immediately it is clear that parish formation groups would be well served to know these theologians, and know them well. So one task for parish formation groups is to make connections in their work on various doctrinal points, to see how our tradition has understood a particular doctrine, for example, and to see how it develops through the ages. All done through prayer, of course — through our continuous relationship with God, a relationship under the Catholic Rule (or regula) of Mass + Office + Devotion. The point is not merely to learn information, but to sow seeds of formation, and water those already sown.
Ok, enough of the background. This post promised “Trinity through Anglican historical theology”. Here is a small example as a demonstration of what is possible. I selected the doctrine of holy Trinity, and found a sentence or two from our five core theologians:
For this is the fullness of our joy, than which there is nothing greater: to enjoy God the Trinity in whose image we have been made.
(Augustine, De Trinitate, I.8.16)
We believe that the divine presence is everywhere and that ‘the eyes of the Lord are looking on the good and the evil in every place.’
(Benedict, Rule, 19)
God is that than which nothing greater can be thought.
(Anselm, Proslogion, 2)
The fullness of joy is to behold God in everything.
(Julian of Norwich, Revelations, 35)
Being is present and manifests itself in every particular being, but most of the time we may miss it altogether. We have already described the revelatory situation in which, so to speak, our eyes are opened to Being, and this happens because Being has itself grasped us and communicated itself to us.
(John Macquarrie, Principles of Christian Theology, 9.34.12)
Between these five thoughts, there are connections here to be made — the ground is fertile! Of course other sentences could be selected — that’s all part of the formative possibility and opportunity, especially given how superb our theological tradition actually is. And opportunities abound amid the theology for direct reference to holy Scripture, such as And this is eternal life, that they know thee the only true God, and Jesus Christ whom thou hast sent (Jn 17.3). That can be reflected upon alongside the thoughts of Augustine, Benedict, Anselm, Julian, and Macquarrie.
No matter the particular selections, the task in our parishes is to join the conversation started by our core theologians (a conversation that is already latent in our experience through participation in liturgical life via The Book of Common Prayer). In this case, the task is to explore devotionally the doctrine of Trinity along the lines suggested by our theologians through use of their language in these five thoughts. Their specific language ought be the point of devotional departure. Here, we see the discussion about Trinity could easily segue into a discussion about the nature of revelation. Segues and tangents, too, are the point. These have to be prayed with, privately as well as corporately. It might be that parish formation groups might explore these kinds of questions:
What do we make of these ideas?
How are these similar? or different?
What are the claims made about God?
How do these impinge upon our prayer life?
Each of the five theological thoughts is pregnant with Christian meaning. Each awaits our lectio divina. In their own way, each thought is an icon. Each issues in a profound recognition of Christ, who Himself is the Perfect Icon of the Father. We are invited to sink into these icons — to sink into Being — and follow where the Holy Spirit leads, and how He leads. We are invited to live with God, to become more like God (theosis).
