The totality of the wondrous events performed by God, in order to bring man after his disobedience back to His house and make him His own once more, is called divine economy or dispensation: ‘The divine economy of our God and Savior is the raising up of man from his fallen state and his return from the alienation produced by his disobedience to intimacy with God’ (St Basil).
This reality of our salvation in Christ is what we experience at every Divine Liturgy, for which we give thanks to God: ‘The awesome Mysteries which are performed at every assembly of the faithful and which offer salvation in abundance are called the Eucharist [‘thanksgiving’] because they consist of the recollection of many benefactions, and reveal to us the culmination of divine providence’ (St John Chrysostom). The Divine Liturgy is the sacramental re-living of these things and the ‘recapitulation of the entire divine economy’. That is why at the end of the Divine Liturgy of St. Basil the celebrant says: “The Mystery of Your dispensation, O Christ our God, has been accomplished and perfected.’
The mystery of the divine economy was made manifest at the same time as man’s disobedience. The Master who loves mankind ‘at once saw the fall and the magnitude of the wound, and hastened to treat the wound so that it would not grow and turn into an incurable injury…spurred on by His love, not for one moment did He cease to provide for man’ (Chrysostom). Through wonderful deeds and prophetic words, God prepared man to partake in the fullness of life and love.
