Purely by accident, Fred Sanders and his thoughts of the Trinity – specifically how it is uniquely revealed and its importance for how we handle thinking and telling about the Trinity – feature today. They are worth reflecting on. Careful thought here will prevent the presuppositions of skeptics carrying undue weight.
It’s from a very useful blog which I visit frequently The Scriptorium Daily.

1. The Revelation of the Trinity is Bundled With The Revelation of the Gospel. God published both at the same time, in the same ways: more obscurely and by way of anticipation under the old covenant, more luminously and by way of fulfillment under the new. The answer to the question, “was the Trinity made known in the Old Testament” runs parallel to the question of whether the gospel was. In both cases, Trinity and gospel, we must account for two factors: the consistency of God’s entire work of salvation, and for the newness in the revelation of “the mystery which was kept secret since the world began, and that in other ages it was not made known to the sons of men, but now is.” Epangel is not evangel, but they are both constitutive of God’s one message of salvation.
2. The Revelation of the Trinity Accompanies Salvation. Though it can be stated propositionally and in the form of information, it was not given primarily as information. Rather, this knowledge came along with the carrying out of God’s work of salvation. God saves, and further, wants the saved to “understand the things freely given us by God.” God did not hand down statements regarding the Trinity, but extended his arm to save, an action which by design brought with it knowledge of, and about, the one doing the saving. As B. B. Warfield wrote, “the revelation of the Trinity was incidental to, and the inevitable effect of, the accomplishment of redemption.”
3. The Revelation of the Trinity is Revelation of God’s Own Heart. Theology, broadly considered, is knowledge of God and of all things in God; “all things” are accounted for by a great many doctrines. But the doctrine of the Trinity is theology proper, knowledge of God in se. Thus its focus is not on those aspects of the divine nature which are knowable by the things created or of God in relation to things outside of him; those things are spoken of in Scripture substance-wise, according to God’s one nature. But the doctrine of the Trinity is a statement about God’s interior life, requiring statements relation-wise, internal to the divine being, describing the Father and the Son and the Spirit as they stand toward each other. Prepositions will be decisive in here: “That true and absolute and perfect doctrine, which forms our faith, is the confession of God from God and God in God” (Hilary of Poitiers, On The Trinity, V:37).
4. The Revelation of the Trinity Must Be Self-Revelation. This knowledge cannot be delegated or delivered by proxy. Hilary of Poitiers again:
Since then we are to discourse of the things of God, let us assume that God has full knowledge of Himself, and bow with humble reverence to His words. For He Whom we can only know through His own utterances is the fitting witness concerning Himself.
5. The Revelation of the Trinity Came When the Son and the Spirit Came in Person. In the fullness of time, God sent forth His Son, and sent the Spirit of his Son into our hearts, crying Abba, Father (Gal. 4:4-6). God did not openly proclaim the existence of his Son and Holy Spirit and then send them; but sent them. God did not announce the Trinity; rather the Son of the Father showed up, with their Spirit. “The revelation itself was made not in word but in deed. It was made in the incarnation of God the Son, and the outpouring of God the Holy Spirit” (Warfield).
6. New Testament Texts About the Trinity Tend to Be Allusions Rather than Announcements. The evangelists and apostles write from a background assumption that readers know God the Father because they have met the Son and Holy Spirit. They refer almost off-handedly to this understanding as something already given, not something to be introduced, put in place, or argued for. There is an obliqueness in nearly every sentence on this doctrine in the New Testament.
