Saint Clare: "the glory of the LORD left the threshold of the temple"

Come, you scourges of the city! With that I saw six men coming from the direction of the upper gate which faces the north, each with a destroying weapon in his hand...They stood at the entrance of the eastern gate of the LORD’s house, and the glory of the God of Israel was up above them. Then the cherubim lifted their wings, and the wheels went along with them,
while up above them was the glory of the God of Israel.

-- Ez 9:1-7; 10:18-22

Worship of the Eucharist. In the liturgy of the Mass we express our faith in the real presence of Christ under the species of bread and wine by, among other ways, genuflecting or bowing deeply as a sign of adoration of the Lord. "The Catholic Church has always offered and still offers to the sacrament of the Eucharist the cult of adoration, not only during Mass, but also outside of it, reserving the consecrated hosts with the utmost care, exposing them to the solemn veneration of the faithful, and carrying them in procession."

-- CCC 1378

Besides sacramental liturgy and sacramentals, catechesis must take into account the forms of piety and popular devotions among the faithful. The religious sense of the Christian people has always found expression in various forms of piety surrounding the Church's sacramental life, such as the veneration of relics, visits to sanctuaries, pilgrimages, processions, the stations of the cross, religious dances, the rosary, medals, etc.
