I read some very interesting comments on CWNews (to which if you don’t subscribe, you ought to). Here are the comments of the Secretary of the CDWDS. Read the whole thing, however.
Archbishop Ranjith said that two extremes must be avoided: a liturgical free-for-all in which "every priest of bishop does what he wants, which creates confusion;" or a complete abandonment of liturgical reforms, leading to a vision that is "closed up in the past." Today, he said, those two extremes are becoming more prominent, and the Church needs to establish a middle ground.
Every day, the archbishop disclosed, the Congregation for Divine Worship receives new complaints about serious liturgical abuses, and complaints that local bishops have failed to correct them. If the Church fails to curb these abuses, he said, "people will attend the Tridentine Mass, and our churches will be empty." Liturgical guidelines are set forth clearly, he observed, in the Roman Missal and in Church documents. Now "some discipline is necessary regarding what we do at the altar."
