"The church’s official ‘doctrine of the Trinity’ was not fully formulated until three or four centuries after the time of Paul. Yet when the later theologians eventually worked it all through, it turned out to consist, in effect, of detailed footnotes to Paul, John, Hebrews and the other New Testament books, with explanations designed to help later generations grasp what was already there in principle in the earliest writings.
“But it would be a mistake to give the impression that the Christian doctrine of God is a matter of clever intellectual word-games or mind-games. For Christians it’s always a love-game.”
Wright, Tom. Simply Christian. London: SPCK, 2006, p. 118.
Comment: It’s clear, according to N.T. Wright, that Christian doctrine is more than simply a slow development of simple statements recorded in the Bible. He says here that doctrine is basically footnotes to the Scriptural text. At least when it (the Bible) is expounded properly.
It would seem, then, that Tradition must in this light be measured against Scripture. If the teachings of Tradition are not apparent in Scripture, then they aren’t footnoting anything. Which makes no sense. Pay attention to Wright’s idea of the “love-game” in tension with the “word-game”. If a doctrinal exposition and explanation is not growing out of the love-game, there’s reason to suspect it.
