So, since the current rite of the Church does not do things in the old way anymore, but uses the new way, is the Mass valid?
That would really be the bottom line, wouldn't it?
That is the central bottom line (the consecration is valid as long as the priest does what the Church sets in stone). However, reverence is a virtue often lost today. People are often too concerned about holding hands, banging the bongos, and "looking pretty" to be concerned about reverence at Mass.
The question of validity is not at stake here. Yes, it's valid. I even attend the Novus Ordo on rare occasions when I absolutely have to in order to fulfill my Sunday obligation. But to reduce the matter of liturgy to validity is a very minimalistic way to approach the issue.
Bread and water are valid food, but no exactly nourishing enough over the course of time.
