From the consideration of spiritual creatures we proceed to that of corporeal creatures, in the production of which, as Holy Scripture makes mention, three works are found, namely, the work of creation, as given in the words, "In the beginning God created heaven and earth"; the work of distinction as given in the words, "He divided the light from the darkness, and the waters that are above the firmament from the waters that are under the firmament"; and the work of adornment, expressed thus, "Let there be lights in the firmament."

First, then, we must consider the work of creation; secondly, the work of distinction; and thirdly, the work of adornment. Under the first head there are four points of inquiry:

A1 Whether corporeal creatures are from God?

A2 Whether they were created on account of God's goodness?

A3 Whether they were created by God through the medium of the angels?

A4 Whether the forms of bodies are from the angels or immediately from God.
