ECCLESIA is the Greek word which translates the Hebrew word for ‘assembly’; meaning the whole People of God gathered together in His Name. The same word is used in Latin, and we translate it into English as ‘Church’.
The full meaning of ‘Church’ is, therefore, the “Gathering together of God’s People”. Nowhere is the meaning of this name clearer than in the Mass, when we gather together in Our Lord’s name.
