They've won barring any miracle of God. The chasm between the Traditional Latin Mass and the Ordinary Form of the Mass celebrated in most parishes is so great and the laity so imbued and appreciative of a Protestant ethos in the Mass, I doubt a return to Catholic sensibilities will happen in my life time.
Most Catholics today love the following:
The Protestant horizontal over the Catholic vertical
Protestant fellowship and conversation in the church over Catholic silence and piety directed to God
The Protestant sound and devotional, spiritual qualities of hymns over authentic Catholic Chant
The cult of the personality of ministers and congregants over the exclusive worship of Christ
The use and corruption of the Mass/Liturgy as a vehicle to promote and celebrate human accomplishments
Protestant casualness and triteness over Catholic formality, precision and reverence
Shall I go on?
