IV. Where is the Liturgy Celebrated?
Catechism number 1183
The
tabernacle is to be situated "in churches in a most worthy place with the
greatest honor."61 The dignity, placing, and security of the
Eucharistic tabernacle should foster adoration before the Lord really present
in the Blessed Sacrament of the altar.62
The sacred chrism (myron), used in anointings as the sacramental sign of the
seal of the gift of the Holy Spirit, is traditionally reserved and venerated in
a secure place in the sanctuary. the oil of catechumens and the oil of the sick
may also be placed there.
