St. Padre Pio : You must remember that the Holy Mass has its internal dimension that transcends in its splendor and its majesty the external dimension. By impoverishing the external dimension of the Mass: the liturgy, the altar, one also impoverishes unfortunately its internal dimension within the souls, and this is why your thoughts flee at all time from below the cross of the Lord. Jesus, however, throughout the entire duration of the Mass, is present on Golgotha. If we move away from the altar in our thoughts, in doing so we leave Him there alone.
St. Padre Pio : I’ve already told you that by its impoverishment [the Mass], people have lost faith because they were deprived of the mystery and the awe, the holy awe before the mystery of God. They gained certitude that they can control the functioning of God within His Church, and also within the world. God allows all this in appearance, but He is very grateful to those who were not deceived. He finds in them a real consolation. The liturgical reform has introduced a great number of restrictions to the action of God’s grace and the multiplication of faith, but even more abuses, which are the arbitrary interpretations of this reform and their testing on the faithful: to mar the Mass as much as possible as long as it still pleases the faithful.
