Father Carlo Buzzi, a missionary under the Pontifical Institute for Foreign Missions, explains in his letter that in his mission in Sirajganj and throughout Bangladesh, "we teach the catechism and to be clear we say that every sacrament has four elements: the minister, the matter, the formula, the miraculous event."
At the heart of his disagreement with the proposal of Cardinal Kaspar is precisely what such an action on the part of the Church would say. Father Buzzi summarizes it well:
But taking the route traced by Cardinal Kasper would cause serious harm:His points are all true - though I do not recall seeing others put it quite so clearly - and would be well heeded.
1. It would make the Church superficial and accommodating;
2. One would have to deny the infallibility of the chair of Peter, because it would be as if all the previous popes had erred;
3. One would have to take as fools all those who gave their lives as martyrs to defend this sacrament.
