Why do Catholics celebrate Communion at every Mass, if Christ’s death atoned for sin once and for all?

Full Question

Many Protestants celebrate communion on occasion; Catholics celebrate it at every Mass as an integral part of their worship. If Christ’s death atoned for all sins, why is it celebrated at each Mass?


The Mass holds the place it does in Catholic worship because becomes of the Real Presence of Christ in the Catholic Eucharist. When Jesus has deigned to become present in that manner, it automatically becomes the most important form of worship.

There are many forms of Catholic worship beside the Mass, and the celebration of the Eucharist is not the only part of the Mass. But it remains the case–and rightly so–that the Mass and the celebration of the Eucharist within the Mass are, as Vatican II put it, “the source and summit of the Christian life” (Lumen Gentium 11).

Holy Communion is celebrated every mass because it is the memory of Christ’s death on the cross for our salvation…When the priest says the prayer of the consecration of the bread, he says ” For this is my body” and the prayer of consecration of the wine- “For this is the chalice of my blood of the new and eternal testament, the mystery of faith; which shall be shed for you and for many unto the remission of sins” ” Do this in memory of me”. The prayer of consecration changes the bread and wine into the body and blood of Christ- the transubstantiation! During the Holy Communion every mass we share the body of Christ as we are members of the corporal body of our Lord!
