Simple apologetical advice
Sal asks below about how to talk to someone about returning to Catholicism. I don’t know exactly what to do in that particular situation, but I can offer the piece of apologetical advice that I find most useful: smile. When discussing the Faith with others, I used to be serious, almost deadly serious. It was such a contrast to my normally affable demeanor that I think it threw people for a loop. Now, whenever the subject of religion comes up, I don’t change my tone and I talk about Catholicism like any other subject. It defuses any tensions, and I’ve been surprised at what I can get away with saying — a light touch can make the most difficult of subjects seem palatable.
If you believe that deep down, everyone wants to embrace and live the truth, you have only to show it to them. This is a way of saying that you’re not doing anyone a favor by withholding an uncomfortable truth. Yes, Jesus revealed the Gospel to the Apostles slowly, but he did not hesitate to warn people if they were endangering their souls. Even though a person might not be committing a sin because of ignorance by receiving the Eucharist unworthily, gently pointing her in the right direction is the right thing to do.
From my own experience, I never resented anyone telling me that I could not receive the Eucharist before I formally entered the Church, or that I should go to confession beforehand. If the Fugitive gets upset by a reminder about confession, maybe she’s not ready yet. Not knowing her mind, I don’t know for certain, but she’ll probably react better than you think she would.
Please let us know what happens, Sal — if she does re-enter the Church, I think we should all welcome her back. I’ll keep her and all other fallen-away Catholics in my prayers. They know not what they left.
