Aquinas’s “theology of motion”

Why do things move at all, according to St. Thomas? So that they can be like God: “any moved thing, inasmuch as it is moved, tends to the divine likeness so that it may be perfected in itself, and since a thing is perfect in so far as it is actualized, the intention of everything existing in potency must be to tend through motion toward actuality” (Summa Contra Gentiles 3.22.7). This is a truly universal theory of gravity: all things are attracted to God.
