The eternity of the triune God: preliminary considerations on the relationship between the Trinity and the time of creation

How may we avoid falling into the traps of representations of God as wholly timeless or enmeshed in creaturely time? What may be needed is a Trinitarian account which, in the footsteps of Basil of Caesarea and Calvin's proposals, articulates God's atemporal, eternal presence in time (God the Father), God's eternally temporal presence (the Son), and God's eternally perfecting relationship to creation in its created time (the Holy Spirit). By construing the Trinity not just causally, but as a conversation in which we are made participants, we might gain a richer understanding of God's eternity which, far from excluding time, takes it up within God's own life.
