The concept of 'the rapture' it seems was first invented in the 17th century from one of the manifold translations in the collection of old writings known as the bible.

There's a number of other examples of inventions/modifications to 'god's word' or 'scripture' as adherents like to call it.

Within my own living memory, christians, esp catholics, were forbidden to eat meat on Fridays or they'd go straight to hell

A pope changed this rule so eating meat was allowed.

However, I don't know if this same pope enabled those previously sent to hell for breaking the old rule to leave hell & go somewhere else - anyone know?

Another example is clerical celibacy apparently ok for clergy to marry until the 4th century then banned afterwards.

St Christopher got the sack too!
