Can you imagine how first century Christians felt when Peter, Paul,James, Thomas, Matthew -the whole bunch - started to die. Nicodemus, Mary the Mother, Mary Magdalene? It must have been such a blow to expectations. The Bible does not focus on this. If there were no problem to the church, John of Patmos would never have written Revelation to give hope. Christian hope is depressing when viewed in this light. I wonder why Christians stayed in the church. Just as with 1975, I expect many Christians decided to go back to their native religion.
The Bible is written from the victor's point of view. Maybe archaeologists will find a manuscript written by those upset Christians. The expectation of immediacy must have presented a very different church from a church not knowing when Christ will come.
