We have already discussed this. Pneumatology is relatively autonomous because it cannot be derived from christology. The elevated Christ is present in all things. All things are filled with the meaning and power of his saving work. This is a spiritual reality - a reality in and through the Holy Spirit, or in other words a reality that exists in the mode of the Spirit.
Salvation goes into existence and is given form in the flesh.
It is God himself in the special form of his revelation. Salvation is the unio mystica cum Christo . The kingdom that is grounded in the reconciling work of the Messiah on the cross is worked out in the present by the Holy Spirit. The salvation that Christ obtained for us is present now, but in the mode of the Spirit. In other words our salvation is concealed in the flesh.
