Not sure if every college offers this, but I majored in Interdisciplinary Studies! My degree let me pick 2 main areas of focus and 1 minor. It's different than double majoring; you're not taking on double credit hours since you're not doing the full coursework of two majors. Instead, you're doing basically half a major of each focus area, credits-wise. I think it made me very well-rounded and gave me a lot of flexibility in what I want to do. Some people pick focuses that go hand-in-hand, like Film and Creative Writing. Other people who have a huge range of interests have picked totally differing focuses. I knew one guy who did Comp Sci & Theater. Doing that can give you a really unique perspective at the intersection of two subjects. My only caution is that this major translates less directly into a specific job after graduation. But they do teach you how to market yourself and your skills before you graduate in the senior Capstone course. Could be a good way to explore your interests while still getting a degree!
Since you're passionate about Religion and Philosophy, you could choose those as your areas of focus! They usually make you choose a minor as well to make sure you're getting depth in a subject, not just breadth. Just make sure to get some sort of internship or practical experience in one of your areas before you graduate, if possible. I made the mistake of kinda coasting thru my degree without going for internships, so it's taken me a little longer to build experience. But I think you truly can make any major work for you eventually, as long as you're putting the work in. Experience seems to end up mattering more than the specifics of the subject. I know someone doing a Master's in folklore studies in Florida of all places, and she's getting plenty of opportunities! Follow what you're interested in and everything will fall into place. :)
Interdisciplinary Studies can seem kinda impractical since it doesn't create a specific career path for you immediately. But I think it becomes really useful in the long run, since employers will like to see versatility and well-roundedness. In my mind, it's kinda the modern equivalent of being a "Renaissance Man" getting knowledge in different areas.
