(Note: this post mostly applies to Protestants, IMO, but perhaps there may be analogues within other Christian traditions, I don’t know.)
Something I’ve observed a number of brothers falling prey to: marrying a woman not from their own particular denomination, but from a more liberal one from the same tradition.
For instance, a brother from, say, the Lutheran Church – Missouri Synod, meeting a nice fellow Lutheran girl, but one from within the Evangelical Lutheran Church of America, deciding to pursue a relationship with her. (Or, to use a Canadian equivalent, a brother from the Lutheran Church – Canada, pursuing a Lutheran gal from the Evangelical Lutheran Church in Canada.)
After all, she’s a fellow Lutheran, right? As long as she’s not like some tattooed slut priestess like Nadia Bolz-Weber, surely, it doesn’t matter, right?
Wrong.
It always matters.
Might as well be unequally yoked, frankly.
Because unless she converted to your more confessional, conservative, traditionalist Protestant denomination of the same tradition as her own, prior to meeting you, she’s only doing it so she can be with you.
Which means she brings all her baggage with her – all her more progressive, anti-traditionalist POV with her, into your flock.
That makes her a Trojan horse. A wolf in sheep’s clothing.
And she’s hardly likely to be particularly submissive and deferential, compliant towards you.
Don’t do it.
And keep on your guard against such women brought into your fold by foolish brethren.
Don’t trust them unless they appear to have had a full change of heart and mind.
Which they won’t have.
Wolves in sheep’s clothing.
They’ll push their husband and your denomination in a more progressive direction.
Keep your eyes on them, always. Watch for promotion of heretical ideologies, or a push for more ‘peace’ rather than conflict against heresy / societal promotion of prog ideals / policies.

The only religious doctrine any woman needs to know is “Be silent in church and submit to your husband”. One theologian per family is enough.

What Dave says. And how many such women are there ANYWHERE in the Western world, in ANY Christian denomination?
Exactly.

Exceedingly few, alas…

I’ve been to a couple of Wisconsin Synod Lutheran churches (more conservative than LCMS). They bragged about parishoners daughters entering the military during announcements.
Virtually no churches are conservative in any meaningful sense. Those that are would be called “cults.” Maybe a few independent Baptists, some Latin Mass Catholics, old order Amish, I don’t know. How many churches require women to cover their heads (once nearly universal). Almost none.

Regarding WELS, I have a sample size of two congregations and I saw many good things in their churches. Still it was striking. They insisted e.g. on young earth, 6-day creationism (ok with me I’m not picking on them for this) but a daughter going into the military is a good thing to be announced proudly. So weird – they’re so out of the mainstream secular culture on some things but as soon as it’s a PC issue, they’re with the secular culture.

I observe a similar dynamic within some confessing Reformed denominations; e.g. strictly lining up with creationism, as you mention re: WELS, but every young woman attending college / uni, seeking a career…
