The 15th Station, a Catholic podcast network in New Zealand, recently posted an interview with Bishop Patrick Dunn of Auckland about the introduction of the Missal in the country, which he says has been "seamless," for the most part. The key was lots of preparation, Bishop Dunn says. It appears that paid off, for he adds in the interview that "people also appreciate the grace of the new translation and are seeing the Scriptural allusions in the prayers."
The Church in New Zealand will introduce the rest of the revisions the first Sunday of Advent.
Listen to the interview.
