Can I be Christian and disagree with traditional Christian teaching on sexuality?

Yes, in the sense that being a Christian, at its core, has always meant trusting in Jesus—his death, resurrection, and lordship—not passing a test on every single ethical question the same way every other Christian does.

That said, this isn't a reason to treat the question as unimportant or settle it too quickly. Christians across history genuinely disagree about how to understand and apply the Bible's teaching on sexuality, and honest wrestling matters here—not just picking whichever conclusion feels most comfortable.

Paul's letters actually address disagreement among sincere believers directly: "Accept anyone who is weak in faith, but don't argue about disputed matters... Let each one be fully convinced in his own mind" (Romans 14:1, 5). That passage was originally about food and holy days, not sexuality, but the underlying principle—charity toward believers who reach different conclusions in good faith—is one many Christians find instructive here too.

If you're in this place personally, you're not alone, and it's worth finding wise, trustworthy people to walk through it with rather than carrying it in isolation.
