@DadJokes, I think a good point to keep in mind, in order to meet your spouse with joy and respect, is that being 'mustachian' is just as weird, socially awkward, and flat fucking crazy as being 'religious.' Being deeply into either is not the social norm.
We all bring our own kinda crazy into our marriages. It's just that my specific kind of crazy is obviously very logical, whereas her's is, well, crazy. She of course feels the same, but inverse. I like the Jesus dude, and I do donate 10% to charities of my choosing, but the older I get the more I realize there are vanishingly few objective rights or wrongs in the world. Your marriage is what you forge it out of, though the good ones do seem to have a common theme of shared vulnerability and respect.
Like others have suggested, I'd say you need to be open with your wife, and you need to be curious. Ask her 'why' a lot, in a genuine bid to know her better. If things are going right, she'll be curious back, and ask you why, and want to know you better. And thus, you forge a marriage. It's not always comfortable, but it's almost always worth it.
I’m a Christian husband and I second the suggestion above - lovingly invoke Ephesians 5:22-24. :)
Whooo, boy. All I can picture is my wife lovingly burning all of my shit on the front lawn, in a fiery and pointed lesson on religion and modernity should I ever claim to tell her what to do. But what does it matter? Because she's a goddamn miracle of evolution and/or creation (pick your poison), and she frequently smells good, and she sometimes does that mysteriously feminine thing where she bends over her own knees to clip her toenails, and how do they
do that? It's a mystery, and I love the beating heart of the whole thing.
