“All theological statements win their Christian character only through their connection with Jesus”
“As Christians we know God only as he has been revealed in and through Jesus. All other talk about God can have, at most, provisional significance. In this sense it may be very meaningful and necessary, even a presupposition for the message of Christ. But the way in which God is revealed through Jesus suspends even its own presupposition, so that one can only speak about God himself in that at the same time one talks about Jesus. Therefore theology and Christology, the doctrine of God and the doctrine of Jesus as the Christ, are bound together. It is the goal of theology as well as Christology to develop this connection.”
Here Pannenberg expresses the absolute significance of Jesus Christ for knowledge about GOD. What this means is that all claims to know God (including in its subjective sense) must be evaluated in view of GOD’s self-revelation in Jesus.
What this does not mean is that all previous knowledge about God is to be set aside. God was not silent and inactive until Jesus, the major events throughout GOD’s covenant relationship with Abraham and his descendants also revealed much about the Creator, and themselves set the stage to understand Jesus as the one through whom the Creator is revealed.
The NT gospels intentionally tell Jesus story as part of YHWH and Israel’s story, ‘the God whom Jesus called “Father” was none other than the God of the Old Testament’. So while we cannot abandon the Exodus for example, as a genuinely revelatory event, God’s mission of which this was a part comes to fuller clarity (although not absolute clarity) in Jesus of Nazareth, the Christ. This is the central significance of Jesus for the knowledge of GOD.
