Same here, though we clearly understand the actual canonical laws and state both. It might interest others to know I spent a couple of years looking for the official rules and never found any, any at all. We also ban spouses, and I’ll tell you why. If you watch a boyfriend/girlfriend pair or a husband/wife pair you will clearly see the “knowledge” spouse rarely treats the other like the rest of the group, and that is unfair. Now the opposite sex is similar many of our sponsors* do meet with their candidate/catechumen outside of class. We also pair them for serious discussion during the retreat so similar age and sex are better followed by large age difference but same sex. Opposite sex pairs rarely perform as well. Now lately on what is the “rule” based The RCIA program is generally entrusted to the local Priest who is to follow the Bishops guides. The Priest often entrusts most of these responsibilities to the RCIA Team. When to meet, where to meet, what agenda to use, etc, etc, etc their all the same; rules used to guide the group. Now suppose a pair of 19 year olds tell us they are sponsor/catechumen period. Our response would probably be we do not support that condition as adequate so they will need to appeal to the Priest who has authority over us, and of course they can appeal to the Bishop if the Priest denies them.
- Nothing can be found which indicates the RCIA sponsor has to be the real sponsor at all. For example many candidates have sponsors listed on their baptismal certificates so was the job done before RCIA? Well theoretical the original sponsors commonly called Godparents are still actively involved in the religious teaching. However that is often not the case at all. Several have had the original sponsor travel in for confirmation. Additionally many use a friend or family member for the official sponsor though they used a RCIA sponsor for the education and conversion process.
Now in closing many may complain about these practices but until they can post something from the Church there is no reason to accept one set of rules over the other set.
Hope that helps
