Sections 425 through 432 cover the Liturgy of the Word in a Rite of Welcoming. Here’s the outline:
Presentation of a Bible (optional, 428)
Profession of Faith (429)
General Intercessions (430)
Prayer over the Candidates (431)
Dismissal of the Assembly (optional, if there is no celebration of the Eucharist, 432)
Just a few words on this. The instruction is a brief address by the celebrant to candidates and sponsors “helping them to understand the dignity of God’s word proclaimed and heard in the church.”
Readings are generally those assigned for the day, though appropriate substitutions are allowed. A homily follows.
“A book containing the gospels may be given to the candidates,” according to the rubrics. This may be done with words (such as “Receive the Gospel of Jesus Christ, the Son of God.”) or not. The candidates “may respond in an appropriate way.”
Then we depart somewhat from the post-homily rituals of the Rite of Acceptance (see RCIA 64-67). The profession of faith is recited on Sundays and solemnities (RCIA 429) and the general intercessions follow. “One or more” intentions for the candidates may be added to the petitions. The ones given in RCIA 430 are nearly identical to many found in RCIA 66. An exception makes explicit that these are baptized persons:
That these candidates may come to a deeper appreciation of the gift of their baptism, which joined them to Christ …
A brief prayer (431) concludes the intercessions.
If there is no celebration of the Eucharist, there is a blessing and (yes) a concluding song (432). If the liturgy of the Eucharist is to be celebrated (433), the Mass continues with the “preparation of the gifts.”
Note the pattern established here: the baptized, however uncatechized, are not dismissed from the Eucharist. It’s not even given as an option in the Rite of Welcoming. Show of hands: how many parishes do dismiss the baptized?
