In Eastern Orthodox, Oriental Orthodox, and Eastern-rite Catholic churches, and formerly in Latin-rite (i.e., Western) Catholic churches, the epiclesis (also sometimes spelled epiklesis, since it is a transiliterated Greek word) is that part of the prayer of consecration of the Eucharistic elements (bread and wine) in which the priest invokes the Holy Spirit. Eastern Orthodox theologians hold that the epiclesis is essential to the eucharist -- without it, the miraculous transubstantiation will not occur. Roman Catholics hold that it is not essential.
