So my wife and I were confirmed through RCIA at the Easter vigil and we're going through the process to baptize our children and convalidate our marriage in a few weeks. My mother is a good catholic and the reason why we also came in to the church. I am personally adamant about her being a godmother to my children, but my priest who is administering our sacraments is claiming that only in case of an emergency is a grandparent allowed to be a godparent. I had brought this up twice and was as insistent as I could be without being openly confrontational until today- the parish secretary was on us for turning in our paperwork and so I printed out some stuff that shows canon law allows grandparents and she basically didn't even want to hear it. She told me that she was pretty sure that grandparents can't be godparents either and that no matter, we should just listen to the priest because he is our spiritual adviser. She then called him to confirm that he is right in this dispute (as opposed to one of the other priests in the parish or the pastor). Of course, he stuck to his position and in the moment, I said that I will forgo my mother as a sponsor because our paperwork was approaching deadline status.
However, I am not happy about this situation whatsoever. Being Catholic cannot mean that I don't have certain rights set down by the church because a parish secretary and a man 2 or 3 years removed from seminary tell me I don't. I take this sacrament (and my new faith) extremely seriously so I want the BEST godparent possible for my children. I don't want to go to the pastor and complain and I don't want to be defiant, but I still want to employ my rights as a Catholic. What should I do?
