I was reading Dr. Kwasnewski’s “Noble Beauty, Transcendent Holiness” and he mentioned something that made me think about transparency.
Here, "Liturgy that is totally transparent is invisible and thus ignored, because it does not catch our attention at the very point where the invisible God becomes visible in otherworldly signs and symbols, like light becoming narrative in a stained glass window. Liturgy that is totally accessible is boring, because it is too easy. . . the traditional liturgies (i.e. EF, Byzantine, Divine Liturgy) are not readily intelligible but opaque, multilayered, cosmic in scope, rich in paradox, proclaiming the ineffable divine sacrifice; they are not transparent. . .not readily accessible but exacting, requiring self-discipline, demanding our conversion to something objective, outside of us, prior to us, higher than us, and normative of us.
