Moynahan is a master of the art of creative nonfiction as he moves the story with lively conflicts between various religious and political characters. He illustrates the main points of disagreement between the reformers and the traditional church with quotes from Tyndale's original translation on such matters as transsubstantiation, priests vs. elders, and love vs. charity. Doctrines hang on the difference in meaning of a word or two. But more importantly, lives are at stake. For Tyndale, Christians do not eat the body of Christ during the Eucharist, they do not need a priest for confession, and 1 Corinthians 13 is about love--not charity and the association of charity with donations to the church. There's more of course--the famous Lutheran doctrine of justification by faith crops up in more than one battle.
Moynahan keep us close to the action by pointing to familiar landmarks in the main cities of London and Antwerp but he also keeps us close to the era by judicious quotes from the main characters presented in early modern English.
