In a phrase, don’t dumb down the liturgy:
52. The laudable idea of making Christian worship more accessible to contemporary (people), especially to those insufficiently catechized, should not lead to either a theoretical or practical underestimation of the primary and fundamental expression of liturgical worship, notwithstanding the acknowledged difficulties arising from specific cultures in assimilating certain elements and structures of the Liturgy. In some instances, rather than seeking to resolve such difficulties with patience and farsightedness, recourse is sometimes made to simplistic solutions.
In addition to patience and farsightedness, it’s also a matter of faith, that the liturgy can do the work it is designed to do. The best option is always to do the liturgy well. This is some of the best advice in this document, the Directory on Popular Piety and the Liturgy, which is online at the Vatican site.
