The dismissal of candidates for reception into full communion is inappropriate. The dismissal of catechumens is barely justifiable, especially in cases where the catechuman has been attending mass for a time (in the case of the person for whom I am sponsor, 18 years).
One of our candidates also is staying in church rather than going for the dismissal. She has been through the RCIA process once and got a dispensation from the priest to do it again.
Her husband, however, who is coming into the Catholic Church is leaving for the dismissal.
