There is a legend, or story in the Greek Church I believe, the cave of the seven sleepers. Imagine that were real. Someone fell asleep in a cave somewhere in Europe in the first century AD when Christians were a persecuted sect meeting in homes and Catacombs, with a love for their Lord and one another. The Son of Man having nowhere to lay his head, Peter and John with no gold and silver but a priceless treasure nonetheless.
He awakes and finds 'the church', now persecuting others. 'Heretics' and 'witches' being burned at the stake. Churches excommunicating or persecuting each other, like some farcical game. Emperors, Kings and rulers claiming to be Christian in name but denying Christ in deeds. Wars and crusades being launched in the name of the Prince of Peace.
Sitting in palaces, on exalted thrones, bishops and popes with their concubines and children round them, engaged in private wars and bloodshed. People revering images, statues, carrying little figurines round the city to bless it, something he saw pagans formerly doing. Giant churches, materially wealthy though spiritually perhaps not so. The down to earth fisherman and craftsmen of the 12 apostles of Christ now given way to crafty-tongued men living in palaces, sitting on thrones and lording it over the people, demanding tithes. People sitting in palaces with billions in 'art' treasures squeezing the poor for cash.
The sleeper would be forgiven for thinking he had encountered a different church. But of course those inside the system can't see the wood for the trees. God Bless
