God is three persons and God has created the universe. How many acts of creation are there here? There seem to be three options:
- Each person of the Trinity performs his own distinct act of creation.
- The persons of the Trinity jointly perform an act of creation, and no one person of the Trinity performs an act of creation.
- Each person of the Trinity performs the one numerically same act of creation.
Since a divine act of creation is efficacious, option 1 implies three individually efficacious creative acts overdetermining the creation of the universe. Then if we attempt to secure reference to God as the one who has performed the act of creation, we fail since there is more than one act of creation, just as we fail if we attempt to secure reference to a place as the north pole of the moon of Mars, since Mars has two moons. But arguably identifying God as the creator either of the universe as a whole or of some aspect of it is central among the ways in which our ancestors gained reference to God. I suppose one could try to rescue our ancestors' reference to God by saying that they ended up ambiguously referring to the three persons. But if so, then it seems that we should say, if we use the word "God" as they did, that there really are three Gods, just as if our ancestors stipulated "Tyrolia" to be the north pole of the moon of Mars, then we should say there are two Tyrolias.
Option 1, thus, leads to some form of atheism or of tritheism.
Option 2 has the unacceptable consequence that the Creed is wrong when it says "I believe in God the Father almighty, the creator of heaven and earth."
That leaves option 3.
