Indeed it’s not arrogant to think God could bypass creaturely/secondary causality and directly create photosynthesis and other cellular processes and structures, rather than use a chain involving both divine/primary and creaturely/secondary causality. But, it’s worth hearing the arguments in favor of “double agency.”Look at the apparatus for photosynthesis in the link below including the amazing ATP Synthase set of molecules. Read how many atoms are involved. Even if more is discovered about them, I don’t think it is arrogant to think that these mechanisms could have been made directly in a supernatural way by God’s hand. I praise Him for His creation.
For Aquinas … creatures are what they are … precisely because God is present to them as cause. Were God to withdraw, all that exists would cease to be. Creaturely freedom and the integrity of nature, in general, are guaranteed by God’s creative causality … For Aquinas, God is at work in every operation of nature, but the autonomy of nature is not an indication of some reduction in God’s power or activity; rather, it is an indication of His goodness. It is important to recognize that divine causality and creaturely causality function at fundamentally different levels. In the Summa contra Gentiles, Aquinas remarks that “the same effect is not attributed to a natural cause and to divine power in such a way that it is partly done by God, and partly by the natural agent; rather, it is wholly done by both, according to a different way, just as the same effect is wholly attributed to the instrument and also wholly to the principal agent.”
The above comes from an essay at the Catholic Education Resource Center website.
Similarly, the following comes from an essay at CatholicIreland.net
But how does God act in a world so well described by science? The classical Christian view developed by Thomas Aquinas, based on the idea of ‘double agency’, distinguished between primary and secondary causality. God is the primary cause of all that exists and he works through the secondary causes of the natural world, which science studies. God’s sovereignty over nature is exercised always through the use of secondary causes, through natural laws and human agency, to achieve his purposes, without infringing on the freedom of his creatures. This means that God’s activity is always mediated through secondary causes. He does not interfere with the laws of nature; rather, God acts to devise and implement the laws that generate new patterns of complex beauty and order. The two kinds of causality are required for a complete description of the real, but they are on a completely different level; scientific and theological explanations are independent of one another. We cannot say how God acts because divine causation is very different. There is no ‘causal joint’ between God’s action and events in the natural world and there are no gaps in their scientific account. God acts ‘behind’ the systems of cause and effect at a level not amenable to physical description.
