The Consilium takes pains to present the case for lay people to receive Communion under both forms. One element often missing from catechesis (at least in the parishes of my memory) is the link between the notion of covenant and the Precious Blood.
32. Holy communion has a more complete form as a sign when it is received under both kinds. For in this manner of reception (without prejudice to the principles laid down by the Council of Trent, [See Council of Trent, sess. 21, Decr. de communione eucharistica cap. 1-3: Denz-Schon 1726-29.] that under each element Christ whole and entire and the true sacrament are received), a fuller light shines on the sign of the eucharistic banquet. Moreover there is a clearer expression of that will by which the new and everlasting covenant is ratified in the blood of the Lord and of the relationship of the eucharistic banquet to the eschatological banquet in the Father’s kingdom (see Mt 26:27-29).
Once the local bishop is satisfied, and catechesis has taken place, the expansion of offering the Cup is granted in thirteen instances:
From now on, therefore, at the discretion of the bishops and preceded by the required catechesis, communion from the chalice is permitted in the following cases, granted already by earlier law [See Sacred Congregation of Rites, Rite of Communion under Both Kinds, 7 March 1965, no. 1.] or granted by this Instruction:
1. to newly baptized adults in the Mass following their baptism; to confirmed adults in the Mass of their confirmation; to baptized persons who are received into the communion of the Church;
2. to the spouses in the Mass of their wedding;
3. to those ordained in the Mass of their ordination;
4. to an abbess in the Mass of her blessing; to the consecrated in the Mass of their consecration to a life of virginity; to religious in the Mass of their first profession or of renewal of religious profession, provided they take or renew their vows within the Mass;
5. to lay missionaries in the Mass at which they are publicly sent out on their mission and to others in the Mass in which they receive an ecclesiastical mission;
6. in the administration of viaticum, to the sick person and to all who are present when Mass is celebrated, with conformity to the requirements of the law; in the house of the sick person;
7. to the deacon, subdeacon, and ministers exercising their proper office in a pontifical or solemn Mass;
8. when there is a concelebration:
a. to all exercising a genuine liturgical ministry in that concelebration; even lay people, and to all seminarians present;
b. in their own churches, to all members of institutes professing the evangelical counsels and members of other societies in which the members dedicate themselves to God either through religious vows or oblation or promise, and also to all who reside in the house of the members of these institutes and societies;
9. to priests present at large celebrations and unable to celebrate or concelebrate;
10. to all groups making retreats, in a Mass celebrated especially for those actually participating; to all taking part in the meeting of some pastoral commission, at the Mass they celebrate in common;
11. to those listed under nos. 2 and 4, in the Mass of their jubilee;
12. to the godfather, godmother, parents, and spouse of baptized adults, and to the laypersons who have catechized them, in the Mass of initiation;
13. to the relatives, friends, and special benefactors taking part in the Mass of a newly ordained priest.
