Although God and His transcendental character are timeless and eternal, the human experience of them, while we live in the flesh, is inherently transitory. It is in a moment when the heart is elevated and ennobled by the experience of Beauty in art - if one thinks of a transcendent experience one has had with art, whether in hearing music or encountering a masterpiece of visual art, the recollection is inevitably the recognition of a single moment: the reaching of a climactic chord, or the first step into a glorious antique Cathedral. Thus one of the most mystical prayers of the Mass is said by the priest following communion: Quod ore sumpsimus, Domine, pura mente capiamus: et de munere temporali fiat nobis remedium sempiternum (Into a pure heart, O Lord, may we receive the heavenly food which has passed our lips; bestowed upon us in time, may it be the healing of our souls for eternity.) After much preparation, we encounter God Himself in the Blessed Sacrament at a moment: Eternity shut in a span.
