In Reasons to Believe, Scott Hahn, a convert to Catholicism, explains the “how and why” of the Catholic faith – drawing from Scripture, his own struggles, and those of other converts, in addition to from on a regular basis life and even natural science. Hahn shows that reason and revelation, in addition to nature and the supernatural, aren’t opposed to each other; moderately, they offer complementary evidence that God exists. He’s somebody, and He has a personality, a personal style, that may be discernable and knowable.
Hahn leads readers to see that God created the universe with a purpose and a form – a form that may be found in the Book of Genesis and that may be there when we view the natural world through a microscope, through a telescope, or through our contact lenses.
At the heart of the book is Hahn’s examination of the 10 “keys to the kingdom” – the characteristics of the Church clearly evident in the Scriptures. As the story of creation discloses, the world is a house that has a Father, a palace where the king is truly present. God created the cosmos to be a kingdom, and that kingdom is the universal Church, fully revealed by Jesus Christ.
