Don’t want to give tithes

My parents always get on my back about tithes because they find out I’m not returning them. Our church sends some tax documents regarding tithes every January so it’s really annoying when I’m the only one in my house who doesn’t receive one, and they call me out for it. I try telling them I’m not giving my money to the Adventist Church because they use it for things I don’t agree with. They will argue with me and tell me it’s not my money to begin with, “it’s Gods money”.

I hate this idea because it’s trying to force me into feeling guilty about not supporting Gods church when I don’t even believe this is the correct church anyway!(Im secretly agnostic atheist, but have to play along for safety reasons). Sorry for the rant but frustrated.
