Raised in a quintessential Protestant tradition, Eugene's encounter with liturgical worship, and especially the Mass, was breath-taking. His imagination was first set in motion for this piece when he heard the Credo intoned at Grace Cathedral in San Francisco. The drama of this particular piece clearly occurs in the organ accompaniment as the choir and congregation recited the entire credo on a single pitch. Credo received this response on tour in the Czech Republic: ...deep artistic and human expression...the strongest probably provoked by Stravinsky's Symphony of Psalms...and the exciting Gerlitz' Credo (translated from Pojizerski Listy, 11 August 93, Vladmir Havrada, critic).
