This new book presents 50 big ideas every Christian needs to know. Christians can make up their own minds, but they need the facts. Why weren't they taught this from the pulpit?

Reading Time: 3 minutes

Whether you’re a Christian, an atheist, or something in between, you should find provocative ideas in my new book, 2-Minute Christianity: 50 Big Ideas Every Christian Should Understand. Perhaps this will also be a fit for someone on your holiday gift list.

2-Minute Christianity is aimed at open-minded Christians who think that if Christianity is true, it can stand a little critique. The tone is respectful, and the goal is to educate Christian readers, not deconvert them. An honest critique of Christianity should appeal to secular readers as well.

Here are some of the big ideas explored in 2-Minute Christianity.

  • God gave Moses two very different versions of the Ten Commandments (Big Idea #30).
  • God defined the rules for indentured servitude and chattel slavery, the same two forms of slavery found in the early United States (#14).
  • The Bible documents its own evolution from polytheism to monotheism (#35).
  • The “virgin birth prophecy” referred to in Matthew wasn’t about Jesus and wasn’t even about a virgin birth (#36).
  • The God of the Bible was once defeated by another Canaanite god (#46).

The ideas are significant—these aren’t trivial Bible contradictions or copying errors. Each is a fundamental puzzle that questions Christian claims. The book is a short 120 pages.

The layout is part of the appeal. Each chapter is just two pages, has occasional tangents in the margins, and takes just a couple of minutes to read. Here’s an example.

The book and ebook are available now, and I’m giving away the content, one chapter per week for 50 weeks, through the book’s blog, podcast, and YouTube channel.

Do you have contact information for your favorite bloggers, podcasters, or YouTubers? You could really help by spreading the word about 2-Minute Christianity to influencers, whether Christian or atheist. Tell them that I have a free copy of the book for them to critique.

Thanks for your continued support of my work!
