The rite has already explained in section 211 that the renunciation of sin and profession of faith are two inseparable part of one ritual. According to RCIA 223, after the baptismal water is blessed, sin is renounced and faith professed.
RCIA 224 gives three formularies from which to choose to reject sin. Choice A:
Do you reject sin so as to live in the freedom of God’s children?
Do you reject the glamor of evil, and refuse to be mastered by sin?
Do you reject Satan, father of sin and prince of darkness?
Do you reject Satan, and all his works, and all his empty promises?
Choice C separates B’s questions.
In RCIA 225, the celebrant, informed again of each candidate’s name by the godparents, questions the candidates individually. Each candidate is baptized immediately after his or her profession of faith.
[If there are a great many to be baptized, the profession of faith may be made simultaneously either by all together or group by group, then the baptism of each candidate follows.]
And the Creed follows in question and answer format.
Note the preference for the individual questioning and then the immediate baptism. Even with smallish groups of candidates, say three or four, I don’t recall having seen the first option used in many years. What have you readers seen at your Easter Vigils?
