How can I tell my parents that I am gay...........................…

My family and I suppose myself are Roman Catholic + I am also 14 years old. I have learned in a cl tought by the church that they teach that god doesn't hate gays but doesn't exactly agree with their decissions...somthing like that. But my mom and dad don't agree with ity. And my other brother seems to be the only one who doesn't hate gays but jokes about them sometimes. I don't know how my parents will react if I tell them and I am sooo scared. Please Please help! :'(
