Bread for the Mass

What kind of bread can be used at Mass?

Concerning the bread used for the celebration of the eucharist, the General Instruction of the Roman Missal, no. 321, states that, "The meaning of the sign demands that the material for the Eucharistic celebration truly have the appearance of food. It is therefore expedient that the Eucharistic bread, even though unleavened and baked in the traditional shape, be made in such a way that the priest at Mass with a congregation is able in practice to break it into parts for distribution to at least some of the faithful. Small hosts are, however, in no way ruled out when the number of those receiving Holy Communion or other pastoral needs require it..."

The Instruction, Redemptionis Sacramentum describes how "the bread used in the celebration of the Most Holy Eucharistic Sacrifice must be unleavened, purely of wheat, and recently made so that there is no danger of decomposition. It follows therefore that bread made from other substance, even if it is grain, or if it is mixed with another substance different from wheat to such an extent that it would not commonly be considered wheat bread, does not constitute valid matter for confecting the Sacrifice and the Eucharistic Sacrament. It is a grave abuse to introduce other substances, such as fruit or sugar or honey, into the bread for confecting the Eucharist. Hosts should obviously be made by those who are not only distinguisher by their integrity, but also skilled in making them and furnished with suitable tools."
