Mass is not a "family". It is the unbloody reenactment of Lord's sacrifice on Calvary. Statically speaking, the drop in attendance corresponds PERFECTLY with the initial changes to the Mass in the 1965 missal, and the full blown introduction of the protestant supper service, er--I mean the  novus ordo missae, in 1969. It was only a matter of time before our priests began to take all sorts of liberties because the Mass' sacrificial nature is so de-emphasized in the new rite. Receiving Holy Communion standing and in the hand. Altar girls, "Eucharistic ministers", overly casual attire. The "sign of peace". Awful and banal contemporary hymns---to name just a few of the commonplace abuses in today's Masses. There is no reverence or appreciation of what is actually happening on the altar, nor the comprehension that the priest is acting IN PERSONA CHRISTI. And, lest we in the post Vatican II era forget, LEX ORANDI, LEX CREDENDI
