So, the Pope is saying God started the universe with a bang but has left it alone since? What is the difference between the concept of God creating the universe and the concept of Intelligent Design?
If the Pope believes that God did not intend to create Man by deliberate purposeful action, then all of Christianity collapses. That would be a strange thing for the Pope to say.
“What is the difference between the concept of God creating the universe and the concept of Intelligent Design?”
“Intelligent Design” is a very specific formulation that goes something like this.... the universe is very old, and living species are descended via common descent, but evolution is not sufficient to explain the changes necessary, so God has to directly intervene at times.
It is analogous to saying that - Yes, gravity is responsible for the shape of the universe, but it is not sufficient to explain it, so God has to directly intervene at times to hold everything together and keep everything in orbit.
It posits a not very intelligent designer, whose tool to change living species, natural selection of genetic variation, is not sufficient to the task assigned it - necessitating direct intervention.
