This post on Liturgy by Fr. Jay Scott Newman is just awesome. I found it via Off the Record.

"Remember that every liturgy leaves chronological time and enters kairotic time. In chronos we say Good Morning; in liturgical kairos we say Dominus vobiscum. If we do not depart from the texts of the Church, then we stand a fair chance of taking the people with us into the never ending liturgy of the New Jerusalem. This is also why SLOW walking, talking and gestures are important. Same with hiding street clothes under sacred vesture. Ditto for the athletic shoes of the altar boys."

I have attended very few Novus Ordo Masses where the above type of stuff is understood. Please go and read the entire post, it is very good.
