The Church as the Ark of Salvation

[T]he nave, a term derived from the Latin word for “ship” (from which we get the English word naval) .... is the place where the worshipping congregation dwells and is called nave because it represents the “ark of salvation.” .... But the church itself is this ark, too, sometimes referred to as the Barque of Peter, the place where Christians are given sanctuary and are guided on their pilgrimage to the Father’s house.
