Final answer:
The sacramental formula, like the words said in the Eucharistic prayer, is indeed the form of the sacrament.
Step-by-step explanation:
The statement is true. The sacramental formula, such as the words said in the Eucharistic prayer, is the form of the sacrament. In the case of the Eucharist, the words spoken by Jesus during the Last Supper, as recorded in the Gospel of Matthew, establish the sacramental formula for the consecration of bread and wine. These words are a crucial part of the Eucharistic celebration and are believed to bring about the real presence of Christ in the bread and wine.
