Dei Filius, Of God, the Creator of all things, Canon 4

4. If any one shall say that finite things, both corporeal and spiritual, or at least spiritual, have emanated from the divine substance; or that the divine essence by the manifestation and evolution of itself becomes all things; or, lastly, that God is universal or indefinite being, which by determining itself constitutes the universality of things, distinct according to genera, species, and individuals: let him be anathema.
