Here’s a possible typo in MR3. I know others have commented on the few references to those to be baptized as “catechumens” when in fact those to be baptized tomorrow night are the “elect.” It might be that the Church retains some catechumens who have not been “elected.” Given that some Catholics might still not know the terms catechumen let alone elect, what about a suggestion for today’s Prayer IV is to pray simply for “those preparing for baptism,” covering the elect, catechumens waiting for another year, and perhaps infants?
Sit in the purple chair and render judgment: change the words to make it clear? Or not?
Catholic Sensibility 
I would leave it alone. That prayer, and the specific reference to catechumens rather than the elect or those preparing for baptism, is ancient, and I think the form of the ancient intercessions should be left alone absent a grave need, which this doesn’t strike me as being.
We have 5 Catechumens who will remain in the RCIA due to marriage issues this year…3 Elect. It happens. It’s a process, not a time frame. Our Catechumens do need prayer- it’s very difficult to remain in the RCIA when all your desires are leading you to Easter Sacraments after nearly a year…many drop out.
