244. Does the Church need places in order to celebrate the liturgy?
The worship "in spirit and truth" (John 4:24) of the New Covenant is not tied exclusively to any place because Christ is the true temple of God. Through him Christians and the whole Church become temples of the living God by the action of the Holy Spirit. Nonetheless, the people of God in their earthly condition need places in which the community can gather to celebrate the liturgy.

245. What are sacred buildings?
They are the houses of God, a symbol of the Church that lives in that place as well as of the heavenly Jerusalem. Above all they are places of prayer in which the Church celebrates the Eucharist and worships Christ who is truly present in the tabernacle.
