Q. 1. What is the meaning of the word Epiklesis. I never heard of it before.
A. 1. "Epiklesis" (epiclesis) is a Greek word that means "invocation" or "calling upon." This invocation of the Holy Spirit, part of the Eucharistic prayer at Mass, refers to the moment when the priest calls upon the Holy Spirit in preparation for the consecration of the bread and the wine at Mass.
When the priest holds his hands extended over the gifts, you know that he is praying the epiclesis. The exact words of the epiclesis vary depending on which Eucharistic prayer is being used.
At the moment of the epiclesis, the Altar server may ring the bell so everybody will pay attention.
