The Kind of Doctrine the Trinity Is

Fred Sanders ends a recent popular level article on the Trinity by summarizing his response to the objection that the doctrine of the Trinity can't be found in any one verse in the Bible. His point is that we should "think bigger" and not rely only on "smoking gun" proof texts for our understanding of who God is and what he has done:

The Trinity is a biblical doctrine, therefore, in a very special sense: not in any one verse, but as the key to the entire book.
