I’ve been reading and listening to reflections on God and time. I get such headaches when I dwell on this question, but four core convictions come to mind as I consider these conversations again.
(1) Creation as irreducible becoming or processu operis (a work in progress). We exist entirely as an act of “becoming,” an ever-moving process in which we determine ourselves in the present by relating our perceived past (the data of past experience; i.e., memory) to perceived possibilities at which we aim ourselves in the hope of becoming what we wish to be. We are a perpetual hourglass that negotiates between the perceived effects of the past and the perceived possibilities of the future.
(2) God’s self-constituting triune perfections and beatitude are actus purus. In our view, God cannot be reduced to the “becoming” described in (1) above, even if the process is qualified by saying it occurs “necessarily.” God’s self-constituting triune act (the Father’s begetting of the Son, the proceeding of the Spirit, the triune fullness and beatitude of this knowing and loving) cannot itself be subject to temporal becoming; it cannot supervene upon a process that prehends ‘past’ data from which God’s ‘present’ is determined in light of some desire to become in the ‘future’ what he is not ‘now’. To borrow Whitehead’s language (but not how he understands it), we suggest that God’s essential triune act is the “epochal immediacy of an occasion’s subjective indivisible unity,” an infinite specious present, an indivisible occasion of plenitude not composed of successive temporal moments upon whose unending process it supervenes (i.e., it has neither past which it remembers nor future changes it anticipates).
(3) God’s free self-expression in creation is contingent and involves duration. If God cannot be reduced to a processu operis, neither can he be reduced to actus purus as a totum simul. If God’s self-constituting, triune fullness is the living immediacy of an infinite ‘specious present’, it is not on that account intolerant of contingent self-expressive modes of willing and knowing. Thus we believe God’s free self-expression in creation (the creating, sustaining, and knowledge of the world in its contingent temporal actualities) involves temporal duration for God. Time flows from God as we “live and move and have our being in God.”
(4) God’s duration is without loss. The phrase is Robert Jenson’s. I don’t include in it all that he does. I employ it only to say that God’s duration as expressed in (3) is without loss (because it’s asymmetrically related) to the triune fullness expressed in (2). God’s self-expressive act in creation, with its duration and change, is purely expressive of his triune identity. God does not constitute himself dialectically within the economy of creation, though his knowledge of and relation to the world involve change and reciprocal relations such as prayer within an open horizon whose precise unfolding even God does not immutably (fore)know. This openness (for free, creaturely becoming in love) just is God’s free, creative self-expression. Free creaturely self-expression (ultimately in unfailing love and union with God) perfectly manifests free divine self-expression because the latter grounds and guarantees the former. But the entire economy of creation, even the Incarnation itself, only expresses or manifests (rather than determines or alters) God’s self-constituting triune fullness.
