Want to include various religions in my fictional novel… will this get controversial

Sorry I did not know where to post this. But basically I want to include religious stuff to my novel but I’m not religious nor am I knowledgeable about it so I’m searching it up online. But theres just so much info and I know for a fact that my plot wouldn’t be “religiously accurate”. Theres also some mixing between religions which contradict each others beliefs and ugh… I really want to include all elements but Im scared the religious people may get triggered at the inaccuracy and think that I’m mocking or offending them…
