There's another technicality you can exploit. Due to a weird political conflict between early Catholics and Marcionites, (which was a bigger Christian sect at the time) the Catholic church embraced the old testament also as the word of God. It was only a means to distance themselves from Marcionites but this has carried over to all modern Christian sects today. Probably yours to.

This means that you can also use those laws. It states that Jews are allowed to get a divorce, and since Christianity is technically a Jewish sect, includes you. The game rules state that its the husband that must initiate it, though. All it needs is a letter with the words on, so its easy enough to pull off. And no forgiveness by God is necessary since its no sin.
