When I was in the seminary in the late "good old" 1970's at St. Mary Seminary and University in Baltimore, we experienced the heyday (mayday?) of the touchy, feely approach to our Sacred Mass and other liturgies. One of the greatest proponents of this form of celebrating the Mass was the Sulpician priest, Fr. Eugene Walsh, (RIP). He was a very practical and down to earth, gentlemanly priest. I knew him rather well. He advocated for more flexibility in the rubrics of the Mass, creativity from the priest and liturgy committees. He wanted engagement by the celebrant with the assembly and vice a versa.
His own modeling of his preference for Mass was one where you always smiled at the congregation as a priest-presider, had big and generous bodily, liturgical gestures and made the prayers of the Mass your own through "adaptation" even with the Eucharistic prayers.
He has influenced perhaps two generations of priests, my age and those a bit older than me, you know the crowd heading for retirement or death (I include myself in that caustic description). These are the very ones who simply can't stand the "reform of the reform" that Pope Benedict has unleashed on our Church and her liturgies.
Oddly enough, the seminary that I attended which was staffed by Sulpician priests, was not that enamored with Fr. Eugene Walsh (RIP). We studied other so-called liturgical theologians and our worship, although certainly creative, was a bit more formal in our main chapel and not of the touchy-feely, personality driven, congregation-adapted style of Fr. Walsh.
At any rate, we do have two primary schools of thought operating today in terms of how the Mass should be reformed or deformed. Which will succeed? The one the Holy Spirit wants which is the one the Magisterium wants. Time will tell and all of us must wait and see.
