The Venerable Servant of God, His Holiness Ven. Pope Pius XII
“If it was at one time necessary even for validity by the will and command of the Church, every one knows that the Church has THE POWER TO CHANGE AND ABROGATE what she herself has established.”
POPE PIUS XII, Sacramentum Ordinis #3
DECREE OF THE COUNCIL OF TRENT
“It declares furthermore, that in the dispensation of the sacraments, salva illorum substantia, the Church may, according to circumstances, times and places, determine or CHANGE whatever she may judge most expedient for the benefit of those receiving them or for the veneration of the sacraments; and this power has always been hers.” [The Canons and Decrees of the COUNCIL OF TRENT, Trans. Rev. H.J. Schroeder. Charlotte, North Carolina: TAN Books and Publishers, Inc., 1978. Session 21, Chapter 2. Page 135.]
