Quite awhile back I got involved in the Fatima Center. If I had known that they truly were a schismatic group then I would have steered clear of it from the beginning. It's just that they convinced me that they really were in line with church teaching. I signed a petition to the holy father for the "true consecration of Russia" and the full revelation of the third secret. What's worse and (really embarassing to say on phatmass) was that I even went as far as to write a letter to the pope about it and emails requesting these things. I didn't have a nasty tone when going about it and I was respectful in my writing as well. (Just so everyone knows I apologized for requesting these things of him by way of email.)
I did some research on the traditional latin mass and from what I found, the new mass looked invalid so I refused to receive communion there and then eventually stopped attending the new mass, and unfortunately there was no traditional mass around so I wasn't attending any mass for a time.
After a time I turned away from these errors and confessed these sins. On a previous Q and A it said that apostacy and heresy are sins in which one can get excommunicated. Should I be? I was in ignorance of it all.
