In general it says that Scripture is a sufficient guide to salvation, although Scripture says that it is not; it denies the authority of the Church established by Christ; it has no sacrifice of the Mass; it does not believe in confession; it denies Christian teaching on marriage; it rejects Purgatory, and very often its advocates refuse to believe in Hell. But I could go on almost forever. Meantime, if you give me any doctrine taught by one Protestant Church, I will produce another Protestant Church which denies it, save perhaps the one doctrine that there is a God of some sort.
