- Main article: Eucharist (Catholic Church)
In the Catholic Church, concelebration (from Lat., con + celebrare,to celebrate together) is the presiding of a number of priests at the celebration of the Eucharist with either a priest or bishop as the principal celebrant and the other priests and bishops present in the sanctuary assisting in the consecration of the Eucharist. The concelebrants assist the principal celebrant by reciting the Words of Consecration together with him, thus effecting the transubstantiation of the eucharistic elements.They may also recite portions of the Eucharistic Prayer. This article treats principally of the practice in the Latin Rite within the Roman Catholic Church.
