I have been told ever since I was a little shit that when you die you go to heaven first wait in line for St Peter to judge you at the pearly gates? Is this in the Bible? I thought god did judging
Every denomination has a different Bible, with different books they consider Canon. For instance, the Ethiopian Orthodox Tewahedo church has a staggering 81 books. They consider the book of Enoch canon, which almost every other denomination considers apocryphal. Interestingly, the book of Enoch corroborates a lot of information from other apocryphal texts, such as the origin of nephilim.
Neither of these mention St Peter at the pearly gates, though. The biggest addition the Apocrypha makes is a record of someone praying for the dead. Protestants generally still do recognise the Apocrypha, but just as historical records and not authoritative, hence not a part of the Bible.
