A transubstanciação não tem nada a ver com estupidez, mas com fé. Da Wikipédia:
According to Roman Catholic dogma, transubstantiation is the change of the substance of the Eucharistic elements ? bread and wine ? into the body and blood of Jesus (although they retain the physical accidents ? i.e. appearance, taste, texture, etc. (anything observable by science) ? of bread and wine).
The Roman Catholic Church holds that the belief that the elements of the Eucharist become the body and blood of Christ was given to the Apostles directly by Christ.
In contrast, many Protestant churches hold that Holy Communion merely symbolically commemorates Jesus' Last Supper with the disciples; this belief is known as "symbolism," "commemoration," or "transignification."
The Eastern Orthodox Church, like the Catholic Church, teaches that the bread and wine truly become the body and blood of Christ.
Some modernist Roman Catholic theologians sought to interpret transubstantiation as only a change of meaning and not a change of substance, however in 1965 Pope Paul VI mandated the retention of the original dogma of the 12th century. According to his 1968 "Credo of the People of God," any theological explanation of the doctrine must hold to the two-fold claim that after consecration (1) Christ's body and blood are really present and (2) bread and wine are really absent, and this presence and absence is real and not merely something in the mind of the believer.
