Meaning: The quote you've provided touches on a fundamental concept in classical philosophical theism, specifically the ontological distinction between God and the created world. This distinction is crucial for the understanding of theism, and it involves the idea that God and the universe are fundamentally different in nature. The quote also suggests that this distinction is maintained through the conception of God and the world as being of different substances with particular attributes attributed to each.

Classical philosophical theism refers to the philosophical tradition that seeks to understand the nature of God and the relationship between God and the world through rational inquiry. This tradition has its roots in the works of ancient philosophers such as Plato and Aristotle and has been developed and refined by theologians and philosophers throughout history.

The ontological distinction between God and the created world is a central concept in theistic thought. It asserts that God, as the creator, is distinct from the universe that was created. This distinction is often understood in terms of the attributes and characteristics ascribed to each entity. God is typically conceived as being transcendent, eternal, all-powerful, and all-knowing, while the created world is characterized by its contingency, temporality, and dependence on God.

The quote also emphasizes the idea of different substances with particular attributes predicated of each. This concept reflects the traditional understanding of God as a being of a fundamentally different nature than the created world. In classical theism, God is often regarded as a necessary being, whose existence is not contingent on anything else, and whose nature is radically distinct from that of the contingent and finite universe.

Arthur Peacocke, the theologian mentioned in the quote, was a prominent figure in the dialogue between science and religion. He was known for his work in exploring the relationship between scientific understanding and religious belief. Peacocke's writings often engaged with the concept of God as the creator of the universe and the implications of this belief for our understanding of the natural world.

In summary, the quote highlights the foundational concept of the ontological distinction between God and the created world in classical philosophical theism. This distinction is essential for any genuine theism, as it underscores the idea that God and the universe are fundamentally different in nature. The notion of different substances with particular attributes attributed to each entity reflects the traditional understanding of God as the transcendent creator and the created world as contingent and dependent. Peacocke's work further contributes to the ongoing exploration of the relationship between theology and the natural sciences, enriching our understanding of the implications of theistic beliefs for our understanding of the world.
