I know this is a loaded question which will spark a lot of debate and controversy. However my goal is to open a dialog  leading to true understanding. The title is actually a two part question because most will automatically reply YES! as Satan was  originally an angel cast out from heaven. This opens the  second part of the question- Is the Bible the true word of God??

Before you respond I ask you look over all the information provided and then answer the questions.    

 In 1557, while in exile in geneva, Switzerland, a then unknown Clergyman, John calvin, assisted by a handful of Englishmen who had fled the persecution of Bloody mary, undertook to translate the complete Bible.  This made Calvin's Bible the first complete Bible to be translated into English from the original Hebrew and Greek texts.  Calvin and his associates did  far more than a translation.  Their edition contained thousands of marginal notes.  Because words and phrases quite often had several meanngs the marginal explanations were meant to remove all doubt from the mind of the reader. This version has been out of print since 1644

 In 1644 Calvin's Bible was repalced by the King James version because the state needed a Bible that more compliant toit's agenda.

King James was a devout believer in the 'divine right of kings'. Among his many other faults, he preferred young boys to adult women. james enjoyed killing animals. He called it hunting. Once he killed an animal he would literally roll about in it's blood.  Some historians claim he practiced beastiality while the animals layed dying.  James was a sadist and a sodomite. He enjoyed torturing people. He was all these things and much ,much more.

Knowing what King James was  we can easily discern his motives.  James ascended the English throne in 1603.  He wasted no time in ordering a new edition of th Bible in order to deny the common people the marginal notes, and thus the real meaning of many Biblical accounts.  The doctrines espoused in the marginal notes struck terror into the heart of kings and their servants of the church.  So james edited his own version without the marginal notes.  The King James version was and is for all time a government publication.
