CCC 170 We do not believe in formulas, but in those realities they express, which faith allows us to touch. “The believer’s act [of faith] does not terminate in the propositions, but in the realities [which they express].”1 All the same, we do approach these realities with the help of formulations of the faith which permit us to express the faith and to hand it on, to celebrate it in community, to assimilate and live on it more and more.
