I Am He Who Is I Am

Aquinas is using philosophical reason to unpack the scriptures themselves. A passage that would otherwise remain cryptic, I am he who is I am, has some kind of interpretation or clarification through the metaphysical reasoning. There's also Romans chapter eleven verse thirty six for from him and through him and for him all things are. And lastly Revelation chapter twenty two verse 13 I am the Alpha and the Omega, the first and the last. Meaning the source and the goal of all things.
