By Father Roger Landry, EWTN News - St. Paul VI had promulgated the new Roman Missal eight months earlier, but, by the time the First Sunday of Advent came around, the new liturgical books were not yet ready, and so the rollout was rather bungled and confusing, for priests and people alike… In many places, that disarray continued, as some thought that the “new Mass” not only allowed for but demanded creativity. This led to a period of sweeping liturgical instability and experimentation that dramatically impacted Church prayer, architecture, art and music.
