I use ‘oh, my god’ as an expression not of faith, but surprise, of wonder at beauty untouched by ideology or dogma as if caught, and pulled, from a dream.
I exclaim ‘oh, my god’ when stunned not by holy ghosts, but the living, who do kindness as though it were nothing unmindful of securing safe passage into heaven, or paradise.
‘Oh, my god’, I cry, when words fall idle or are muted to quiet reverence. Where twisted skeins of empiric memory, rush in crashing surf of reminiscence and nostalgia.
I am godless, but not without reason ‘oh, my god’ being a slip of historical, idiomatic vernacular. Even as curiosity drives me to understand your own ritualistic, devotional motivations.
Raise the cup, my friend it gives us both what we need. For you, transubstantiation for me a divine and luscious tableaux. For Saint Teresa in her ecstasy no doubt exclaimed ‘Oh, my god’!
