The Latin name for the church (ecclesia) is actually a transliteration of a Greek word that means those duly summoned for an assembly, a public convocation. Thus to gather together is to “be church.” The church building is simply the meeting place for the church, the house of the church. The one who summons us together is God. That call has come to us in so many ways – in baptism, in faith formation, through the example of family and friends, when the day and hour for gathering approaches, when we hear the church bells, or when someone says, “It’s time to go.” What we are to do when we are assembled is to listen and respond to God’s word and to share a holy meal. And this is something we do together, as a holy people summoned by God. God call us as a people.
