Hamartophobia – Fear of Sinning. #Hamartophobia
This is the fear of sinning or commiting a sin. This is also close to or associated with Enissophobia \ Enosiophobia (which both mean fear of criticism or committing a sin), and Peccatiphobia \ Peccatophobia (which both mean fear of sinning or wrongdoing).
As a Christian, we should fear sinning against God, but not the afraid part.
