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.
