Here are some things to think about.
Did you begin working with Lucifer before or after your marriage? If it was before did she fully know all about it?
Perhaps she is frightened by your involvement with Lucifer. Consider it from a mundane person’s point of view. For the past 1500 - 2000 years Lucifer has gotten a LOT of bad press and Christianity has made him out to be the father of all evil. Even if she is not a christian the fact is that all of western civilization is saturated with christian references. Some of the bad press is decidedly secular. Perhaps at some point in her life she watched the movie the Exorcist or at some point listened to the words of the Rolling Stones Sympathy for the Devil. So I think it would be hard for any mundane person from western civilization even an Atheist to not get freaked out and afraid. And if we all are truly honest with ourselves that sense of danger and taboo is one of the things that attracts all of us to the LHP.
So talk to her, listen to her, really listen to her. And if you can’t resolve this somehow. Go to counseling from an open minded marriage counselor.
It does concern me that you want Lucifer to punish her because your wife is someone you made a vow in which to love, and to care for life. The old Gods respect and honor the keeping of vows Also marriage isn’t just a secular thing it’s also a spiritual thing even if your wedding was before a secular judge. The keeping of an oath is an opportunity to ascend spiritually also.
The first thing I would do after listening to your wife is to apologize to Lucifer for your wife’s behavior a and ask him not to punish her. Also ask Lucifer to help resolve this in the Wisest way possible. If you could gently convert her to your side that would be helpful it always helps a marriage if the couple has the same Gods. The emphasis is on gently bringing her to your side.
The next thing I’m going to say is very controversial and will probably piss off a lot of people. Marriage is a partnership between 2 equals and it is hard work. Think of your wife as the heart and soul of your family. You are the head and protector of your family. Being the head of the family does not mean you can lord it over her or make unilateral decisions. Being the head of your family means that you provide Wise spiritual leadership. The best leaders lead though influence. You are also your family’s protector. Of the 2 of you, your wife is the more vulnerable. She is more vulnerable because she can get pregnant and have to go through 40 weeks of pregnancy, hormones fluctuating wildly, then nursing and being a mom. You wife needs to feel safe in her home. As a mundane person she probably feels terrified of you having a altar to Lucifer in the home because on a emotional gut level it goes against 1500 - 2000 years of anti Lucifer propaganda. That emotional gut level understanding happens long after intellectual understanding. It will take a long time.
That is all my thoughts for now. This is a difficult problem and I certainly don’t have the answers. I’ll continue pondering your problem and if I think of anything else I’ll write it. -Blessings
