I am really sorry for what I did. I really am. I desecrated the host while I was in my most sceptical phase, about a few months ago. I remember looking up about it afterwards on the internet, and found out that it is a really grave sin, and that I could get excommunicated. I am not sure if I knew that it was a grave sin beforehand, but I do remember actually feeling really sorry for what I have done for the first time in my life, after finding out that it was a grave sin. I don't know if my parish priest will be happy to accept to enrol me in RCIA once I decide to do so, if I confess about this to him. And not to mention I have to have the pope lift my excommunication. Can anyone please help me? Any advice?
