By Anthony Esolen, The Catholic Thing - The faithful do not conclude that liturgy enlists man’s creative powers at their highest. They conclude that the liturgy may be thus or so, ad libitum. It is a matter of indifference. Many of them then fall into their own motu proprio and stay home and sleep late. Nor do they feel guilty about it. If liturgy may be thus or so, why not belief too? Arbitrium orandi, arbitrium credendi.
