I just read two of Br. Consolmagno’s books, so I can comment on this. He has explicitly rejected Deism in his book, “God’s Mechanics.” Br. Guy is a Jesuit Brother and clearly and explicitly believes in the miracle of the Incarnation, and the intervention of God in the natural order in response to prayer, so how could he be a Deist, or how could he NOT believe that God intervenes by inexplicable means? He was simply stating his belief that God generally uses natural processes to run the world (erosion, natural selection, volcanism, etc.) but intervenes at specific points when necessary. He was arguing against the idea of tying scientific theories to faith, since science changes (few scientific textbooks are still accurate after 25 years) but faith remains constant. Fr. Lemaitre, who formulated the “Big Bang” theory argued in a similar fashion against any attempt to incorporate his theory into orthodox theology, as he said science can always be proven wrong and his theory was no exception. St. Augustine made the same argument.

I think you’re taking Br. Consolmagno out of context based on a single passage you read, Inocente.
