Part 3, section 5 begins:
60. Exposition of the blessed sacrament, either in a ciborium or a monstrance, draws the faithful to an awareness of the sublime presence of Christ and invites them to inner communion with him. Therefore, it is a strong encouragement toward the worship owed to Christ in spirit and in truth.
Ciborium would be the traditional vessel for Holy Thursday. The monstrance is for other times.
In such exposition care must be taken that the signs of it bring out the meaning of eucharistic worship in its correlation with the Mass. This end is served in the case of solemn and prolonged exposition by having it take place at the end of the Mass in which the host to be exposed for adoration has been consecrated. The Mass itself ends with the Benedicamus Domino, without the blessing. In the surroundings of exposition, [See no. 62 of this Instruction.] anything must be carefully avoided that could in any way obscure Christ’s intention of instituting the holy eucharist above all in order to be near us to feed, to heal, and to comfort us. [See St. Pius X, Decr. Sacra Tridentina Synodus, 20 Dec. 1905: Denz-Schon 3375.]
So the Christ’s institution of the Mass is “above all” about feeding people, healing people, and comforting people. So much for deep-sixing Eucharist as meal.
Consider the no-no the Consilium states:
61. The celebration of Mass is prohibited within the body of the church during exposition of the blessed sacrament, all contrary concessions and traditions hitherto in force, even those worthy of special mention, not withstanding.
For, in addition to the reasons given in no. 55 of this Instruction, the celebration of the eucharistic mystery includes in a higher way the inner communion to which exposition is meant to lead the faithful and does not need the support of exposition.
If exposition of the blessed sacrament goes on for a day or for several successive days, it should be interrupted during the celebration of Mass, unless it is celebrated in a chapel separate from the area of exposition and at least some of the faithful remain in adoration.
In those places where a break with long-established, contrary custom would upset the faithful, the local Ordinary should fix a sufficient but not overly long period for instructing them before the present norm takes effect.
