140. Every year, the Church celebrates the great mysteries of the redemption of mankind in the “most sacred triduum of the crucifixion, burial and resurrection”(143). The Sacred Triduum extends from the Mass of the Lord’s Supper to Vespers on Easter Sunday and is celebrated “in intimate communion with Christ her Spouse”(144).
141. Popular piety is particularly sensitive to the adoration of the Most Blessed Sacrament in the wake of the Mass of the Lord’s supper(145). Because of a long historical process, whose origins are not entirely clear, the place of repose has traditionally been referred to as a “a holy sepulchre”. The faithful go there to venerate Jesus who was placed in a tomb following the crucifixion and in which he remained for some forty hours.
It is necessary to instruct the faithful on the meaning of the reposition: it is an austere solemn conservation of the Body of Christ for the community of the faithful which takes part in the liturgy of Good Friday and for the viaticum of the infirmed(146). It is an invitation to silent and prolonged adoration of the wondrous sacrament instituted by Jesus on this day.
In reference to the altar of repose, therefore, the term “sepulchre” should be avoided, and its decoration should not have any suggestion of a tomb. The tabernacle on this altar should not be in the form of a tomb or funerary urn. The Blessed Sacrament should be conserved in a closed tabernacle and should not be exposed in a monstrance(147).
After mid-night on Holy Thursday, the adoration should conclude without solemnity, since the day of the Lord’s Passion has already begun(148).
