36. Communion in Circumstances of Particular Solemnity
This can well be done, for example: by the assembly of the faithful, when they renew their baptismal vows at the Easter Vigil; by young people, when they do the same in the presence of the Church, in a manner in keeping with their age; by bride and bridegroom, when they are united in the sacrament of marriage; by those who dedicate themselves to God, when they take vows or make their solemn commitment; and by the faithful, when they are to devote themselves to apostolic tasks.
37. Frequent and Daily Communion
Since "it is clear that the frequent or daily reception of the Blessed Eucharist increases union with Christ, nourishes the spiritual life more abundantly, strengthens the soul in virtue and gives the communicant a stronger pledge of eternal happiness, parish priests, confessors and preachers will frequently and zealously exhort the Christian people to this holy and salutary practice."91
38. Private Prayer After Communion
On those who receive the Body and Blood of Christ, the gift of the Spirit is poured out abundantly like living water (cf. John 7: 37-39), provided that this Body and Blood have been received sacramentally and spiritually, namely, by that faith which operates through charity.92
In order to remain more easily in this thanksgiving which is offered to God in an eminent way in the Mass, those who have been nourished by holy Communion should be encouraged to remain for a while in prayer.93
