I noticed Fr. Barreiro celebrated a Tridentine Mass. I personally go to a NO Mass. I use a prayer book first published in 1925, it includes prayers to pray at Mass while the priest celebrates Mass. It is in my opinion richer in spirituality than the simple, desert like, stripped prayers one encounters at the Mass of these modern times. I think these modern day prayers lack a great deal which the older prayers contained, and that this is also a contributing factor to the loss of understanding and knowledge of the faithful about the Mass and their Faith.
Discussions before these arrid translations would not have descended to whether or not Jews were saved. Public Prayers from those times included prayers for the conversion of Jews. If it was not necessary to convert them, the prayers would not have been prayed.
How we pray does indeed shape how we believe.
The questions you bring up are exactly what disconcert me. Not only that, but instead of thinking that one has a firm rock to stand on by being Catholic, I increasingly get the sense that it is a constantly shifting sand pile.
"I think these modern day prayers lack a great deal which the older prayers contained, and that this is also a contributing factor to the loss of understanding and knowledge of the faithful about the Mass and their Faith."
Absolutely. And when older prayers are dusted off and used, often they are altered to water them down.
"I increasingly get the sense that it is a constantly shifting sand pile."
Well, the objective of the modernists was to create just that situation, to transmogrify the faith into a shifting and unreliable pile of sand.
