The Ten Commandments are an Echo of Creation

The words "God said" appear ten times in the creation account. In this way the creation narrative anticipates the Ten Commandments. This makes us realize that these Ten Commandments are, as it were, an echo of the creation; they are not arbitrary inventions for the purpose of erecting barriers to human freedom but signs pointing to the spirit, the language, and the meaning of creation; they are a translation of the language of the universe, a translation of God's logic, which constructed the universe.

Joseph Ratzinger (later Pope Benedict XVI),
In the Beginning…: A Catholic Understanding
of the Story of Creation and the Fall

This book is simply wonderful. It's a series of Lenten homilies that Ratzinger delivered. I'd have loved to have been in the audience to receive such wisdom. I can't recommend this book highly enough. We'll see the second half of this paragraph tomorrow, continuing the idea of how deeply embedded we are in creation and creation is in us.
