CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1178–1181

1178 The Liturgy of the Hours, which is like an extension of the Eucharistic celebration, does not exclude but rather in a complementary way calls forth the various devotions of the People of God, especially adoration and worship of the Blessed Sacrament.
1179 The worship "in Spirit and in truth"of the New Covenant is not tied exclusively to any one place. The whole earth is sacred and entrusted to the children of men. What matters above all is that, when the faithful assemble in the same place, they are the "living stones," gathered to be "built into a spiritual house." For the Body of the risen Christ is the spiritual temple from which the source of living water springs forth: incorporated into Christ by the Holy Spirit, "we are the temple of the living God."
1180 When the exercise of religious liberty is not thwarted, Christians construct buildings for divine worship. These visible churches are not simply gathering places but signify and make visible the Church living in this place, the dwelling of God with men reconciled and united in Christ.
1181 A church, "a house of prayer in which the Eucharist is celebrated and reserved, where the faithful assemble, and where is worshipped the presence of the Son of God our Savior, offered for us on the sacrificial altar for the help and consolation of the faithful - this house ought to be in good taste and a worthy place for prayer and sacred ceremonial." In this "house of God" the truth and the harmony of the signs that make it up should show Christ to be present and active in this place.
