Infallibility, per se, covers the formal definition of a Doctrine, which we must believe, by the Pope, in his Office of Supreme Pastor and Teacher of all the Faithful. This gift is extended to the College (or Body) of Bishops who, perhaps in an Ecumenical Council, in union with the Pope, propose, as coming from God, a Doctrine for our belief. For a more detailed explanation of Infallibility, see the Catechism of the Catholic Church, 890-892. See also the Vatican Council document, Lumen Gentium, 25.
How does this freedom from error in the Teaching of Catholic Dogma work? We know, for example, how certain changes have been made to the outward way (i.e. the language and actions) that Mass has been offered. The essence of the Mass, however, is unchanged. Acting in the person of Our Lord, who commanded, “Do this in memory of Me”, Father, our priest, still re-enacts the once-and-for-all Saving Sacrifice of Calvary for our participation; he changes bread and Wine into Jesus Himself, offers Him for us all to the Heavenly Father, Who Himself offers Jesus to us in Holy Communion.
During the coming week we will recall two other great defenders of the Truth: Monday, Convert and Theologian, Saint Augustine of Hippo; Tuesday, Saint John the Baptist, beheaded for publicly defending God’s Laws regarding Marriage. Then, on Wednesday, comes the memorial of Saints Margaret Mary Clitherow, Anne Line and Margaret Ward, three of the Forty Martyrs of England and Wales, all of whom were put to death for hiding, sheltering and protecting Catholic Priests. May their Prayers strengthen all who are called to be our Shepherds!
