First of all, welcome to the forums!! I really hope you enjoy it here.
Second of all, and you don't have to give me any more detail than you're comfortable with, but what kind of "slip ups" are we talking about here? Is it something major like caught drinking alcohol, or something minor like using a swear word?
I just wonder if you're interpreting their requiprements a bit more strictly than they mean them to be, or if your Bishop is being more strict than he needs to be. (coming from someone who has only a cursory knowledge of the process, so I may be way off)
