Going to a Catholic ceremony, but I am not Catholic. Any tips?

go and be yourself. try not to look at the religion ,that won't help you you don't have a relationship you need . you can have it . you have to ask for it . if you ask for here the world come out to see that you get both side . look and see what great length people will go to embrace this relationship you need .God is looking for you . God want you to be His own , giving you all He has to give to you .
