Is this morally wrong in any sense?

Ok I was thinking of joining a Lutheren church near my house mainly because it was closer to my house, well the problem is my mom is catholic and my dad had no religion but I was baptise under methodist but I also have the beliefs in catholicism such as no meat on fridays during lint and no birthcontrol, ect. anyways to be honest I don't know what my true religion is, but the main question is going by what I said, is it ok morally to join a lutheren church?
