This is only my opinion, but in the spirit of what Pope Francis teaches repeatedly that the church is a field hospital for sinners, what is to be gained by ignoring your mother’s anniversary? It sounds like she’s been away from the Church for so long that it’s a stretch to even call her Catholic anymore. I can speak to this better than some, as I, myself, fell away for 30 years. If it were my mother, I’d buy her a gift and at the same time, perhaps go to your parish priest and obtain whatever paperwork or pamphlets that he can provide you about the annulment process. I’d put all this info into a little card or envelope and give it to her along with the gift. On the card, I’d express my deep love for her and how thrilled you’d be to one day be able to attend Mass and receive the sacraments with her–your much loved mother–at your side. Love always has a deeper impact than sanctimonious behavior.
Also, I suspect that if there is one thing that may well be changed at the synod the pope and bishops are having this Fall, it might well be something to do with the annulment process–perhaps to make it less daunting and time consuming. Obviously, the Pope cannot change what Jesus said about marriage being permanent–but he could indeed and very well may simplify the annulment process. I don’t pretend to be able to interpret the Pope’s mind and thoughts, but there’s a lot of positive things he could do with the annulment process that would make it less daunting and allow many lapsed Catholics to return home to the Catholic Church. Just my thoughts—:shrug:
