Canon 27. If anyone says that there is no mortal sin except that of unbelief, or that grace once received is not lost through any other sin however grievous and enormous except by that of unbelief, let him be anathema.
Doesn’t matter. If what you believe is true, I can anathema myself all I want, and I’m still going to heaven.
I have always accepted Jesus as my Lord and Savior. I never remember a time when I didn’t. Therefore, I am going to heaven even if I don’t believe I am guaranteed to go to heaven.
There is no belief I can hold, no action I can do, no mortal sin I can commit that can keep me out of heaven.
Love,
