Full title: "Four Blood Moons: Something is About to Change."
Hagee is one of those unique type of fire-and-brimstone tele-vangelists that only the United States can seem to create. Among his peers he is perhaps particularly noteworthy for his outspoken defence of Israel, and his calls for 'good Christians' to rise to advocate for and give active support to Israel. Tying his affection for Israel with numerology and a particularist reading of 'astronomical' symbolism (Hagee strives to clarify that his work is NOT astrology), he attempts to convince readers that the world is on the verge of a significant moment in Christian history that presages the return of 'the Saviour'.
Even as someone with a less-than-extensive knowledge of Biblical scripture, Hagee's book is rife with contradictions and questionable interpretations. Once I'm finished the book, I will strive to document these.
Here's a link to a related article by Hagee written for the Christian Post.
Hagee's interpretations are not only controversial among those who decry use of the Bible as prophetic (or fact), but among Christians as well. For instance, see the Beginning and End blog's and End Time blog's refutation of the 'four blood moons' interpretation by Hagee.
