In what has just been described, an all too widespread opinion today holds that so-called creativity, the action of all present, and the relationship of group members who know and address one another are the genuine categories of the conciliar understanding of the liturgy. Not only chaplains, but sometimes even bishops, have the feeling that they have not remained true to the Council when they pray everything as it is written in the Missal; at least one “creative” formula must be inserted, however banal it may be.
The evil of banality!
And the civil greeting of those present, with friendly wishes at the dismissal, has already become an obligatory ingredient of the sacred action which anyone would hardly dare to omit.
I've seen priests get so caught up in the opening monologue that they forget the opening Sign of the Cross, and so caught up in closing the show they forget the final blessing.
