Fred Sanders is an evangelical theologian who specializes in the doctrine of the Trinity. He recently wrote Theses on the Revelation of the Trinity in which he discusses a number of items in relation to how we should understand the revelation of the Trinity and how we should engage in theologizing about this reality. Here are the eleven theses he posted. Be sure to read the full article for his discussions on each of these items. I give Sanders' comments on theses 10 and 11 as I thought they were especially moving.
1. The Revelation of the Trinity is Bundled With The Revelation of the Gospel.
2. The Revelation of the Trinity Accompanies Salvation.
3. The Revelation of the Trinity is Revelation of God’s Own Heart.
5. The Revelation of the Trinity Came When the Son and the Spirit Came in Person.
7. The Revelation of the Trinity Required Words to Accompany It.
8. The Revelation of the Trinity is the Extending of a Conversation Already Happening.
9. The Revelation of the Trinity Occurs Across the Two Testaments of the Canon.
11. Systematic Theology’s Account of the Trinity Should Serve the Revelation of the Trinity in Scripture. Christian theology should be a humble discipline, pointing from itself back to Scripture as much as possible. It may need to invent new terms, make careful distinctions, and construct conceptual schemas to make sense of the evidence; I’m neither justifying theological laziness nor criticizing scholastic predecessors (who tended to obey this rule more than moderns have). But a systematic rendering of the Trinity should be careful not to rocket out of the orbit of the biblical content it is designed to explain. It ought to eventually lead back to good reading of the text. Scott Swain argues that “doctrinal propositions apart from the exegetical arguments that they summarize are at best ambiguous,” and this is especially true in trinitarian theology, where the dynamics of the arguments can be so conceptually seductive as to alienate theological affections from Holy Scripture. Because of what the inspired text is –the words of the Father and the Son speaking in the Spirit– readers may actually come into contact with the triune God in them. The systematic theology of the Trinity ought to help open that possibility, not occlude it.
