The phrase "celebrate mass" is commonly used in the Catholic Church to describe the act of performing the Eucharistic liturgy. However, there are several alternative phrases that can also be used to describe this religious ceremony. One alternative is to simply say "say mass," which is a slightly more casual way to reference the act of performing the liturgy. Another option is to use the phrase "offer mass," which emphasizes the priest's role of offering up the bread and wine as a sacrifice to God. Finally, some may refer to "concelebrating mass" when two or more priests participate in the ceremony together. Regardless of the phrasing used, the celebration of mass remains a central part of Catholic worship.
