How did King Henry VIII's break from the Church differ from Martin Luther's?
I might be wrong but if I remember correctly, Luther opposed the idea of priests or the Pope being the only source of divine knowledge, indulgences or otherwise "buying" your way into heaven and he advocated that the Bible being transcribed into languages other than Latin so that any man or woman could read and learn from it. Henry wanted a divorce and the wealth that would come from the dissolution of the monasteries and abbeys - in addition to the power that would come from being both the head of church and state.
I think you can say that Luther never wanted for the church to break up. He realized that some things were not going well (as Lievre said). He wanted to reform it. He didn't have the intention to make up a new religion. It just did in the end, because the authorities had no intention to change anything.
Henry VIII. on the other hand was were openly attacking the pope ans everyone, who stood in his way. His opinion counted and only his.
