A summary of a paper given in the RIST seminar, King's College London
In his Philosophical Consolation, Boethius defined ‘eternity’ as ‘totally simultaneous and perfect possession of interminable life.’ Where Meister Eckhart (ca. 1260-1329) refers to this quote, he highlights Boethius’ dynamic concept of life (vita) with a God who simply is present: ‘God is “beyond” eternity because of his presentiality.’ Now, how can be beyond eternity, beyond being endlessly divine? Eckhart’s reasoning starts with an explanation of Ex. 15:18: ‘The Lord will reign for ever and beyond.’
This hyperbolic ‘and beyond’, which goes further even than ‘for ever’, caught Eckhart’s attention. To Eckhart, the conventional reading of eternity reduced to a radical presentiality was ‘not subtle enough’. Whereas for Thomas Aquinas neither have there been, nor will there be infinite things in reality, since, as he understands his Catholic faith, generation has a beginning and will have a definite end and therefore cannot be infinite, to Eckhart, Ex. 15:18 ‘plainly and briefly intends to say that God’s kingdom will always and infinitely stand beyond any measure of counting or conceiving’. In what is almost no more than a further allusion, Eckhart adds what turns out to be the core of his explanation: ‘What goes for God’s knowledge is equally true about his kingdom and rule. “We will walk in the name of the Lord our God forever and beyond that” (Mi. 4:5).’ Whereas before Eckhart was speaking of divine knowledge only in which God understands infinite potentiality and actuality, the reference to Mi. 4:5 transfers divine knowledge to ‘us’, to God’s creatures. God’s being beyond himself means that he is enabling ‘us’ to walk in God’s name forever ‘and beyond’. What this walking of creatures in God’s name entails is further expounded in the newly published first volume of Markus Vinzent, The Art of Detachment, Meister Eckhart: Texts and Studies (Leuven, 2011):
