Honoring spiritual autonomy is supporting your partner's worship, faith, or spiritual practice as a freely chosen part of who they are, without subtle or overt pressure to change, convert, dilute, or abandon it.
It treats your partner's relationship with the sacred — their religion, their search, or even their settled unbelief — as theirs to hold, recognizing that faith is often not a hobby but a load-bearing wall of identity. It is warmer than mere tolerance (gritted-teeth permission) and more engaged than indifference ("I don't care what you believe" can be its own dismissal). It also is not the abandonment of your own convictions: an atheist need not pretend to believe, and a devout partner need not soften their faith, to grant the other the dignity of theirs. The flag lives in the autonomy, not in agreement.

Why it matters
Why it matters. Pressuring a partner's faith — even gently — sends the message that the real you is a problem I'd like to solve. Honoring autonomy says the opposite, and it defuses the slow campaigns and holiday negotiations that grind mixed-belief couples down.
How to cultivate it
How to cultivate it. Get curious about the function of the practice, protect its rhythms, ask to understand rather than to win, and talk about high-stakes intersections — holidays, weddings, children, death — before they arrive as crises.
The honest caveat
The honest caveat. The evidence is supportive but largely indirect — autonomy support and respect are well-studied 123; the application to spiritual autonomy is a reasonable extension, and the interfaith and sanctification work relies on self-report and cannot easily separate cause from effect 456. Much of the practical wisdom here is craft knowledge, sturdy but not laboratory-certified.
