Irenaeus [130-202] . . . taught that the whole of creation flows from the very “substance” of God.  All things carry within them the essence of the One. Irenaeus . . . signaled his concern about the doctrine of creatio ex nihilo,creation out of nothing. . . . This was to become the standard of Western Christianity’s approach to creation. Creation would be viewed not as coming forth from the substance of God but as fashioned from afar by a distant Creator, made out of nothing from on high.
Irenaeus intuited that this would be a disaster, that to neutralize matter, to teach that creation does not come from holy substance, would lead to the abuse of creation. It was a convenient “truth” . . . [meaning] that the empire could do whatever it wished to matter. Matter was not holy. It had not come forth from the womb of God’s Being. Rather it was made from nothing. It was essentially devoid of sacred energy. So, every imperial mind could ravage the earth’s resources with impunity. It could disparage the rights of creatures and subordinate the physical well-being of its subjects. Religion had become the accomplice of the state’s subordination of the earth. It had sanctioned the separation of spirit and matter.
.. God is both transcendent and immanent. And the work of Jesus, he taught, was not to save us from our nature but to restore us to our nature and to bring us back into relationship with the deepest sound within creation. In his commentary on the Prologue to St. John’s Gospel, in which all things are described as spoken into being by God, Irenaeus sees Jesus not as speaking a new word but as uttering again the first word
.. He describes Jesus as “recapitulating” the original work of the Creator
If you would learn more, ask the cattle,
Seek information from the birds of the air.
The creeping things of earth will give you lessons,
And the fishes of the sea will tell you all.
There is not a single creature that does not know
That everything is of God’s making.
God holds in power the soul of every living thing,
And the breath of every human body.
—Book of Job 12:7-10
.. From the beginning of the Bible to the end, it is clear that a loving God includes all of creation in God’s Kingdom.
.. In the Genesis story, God’s love, beauty, and goodness overflow into creation; and all creatures, including humans, are living peacefully in God’s presence. Isaiah prophesies the “peaceable kingdom” to come (11:1-9; 65:17-25), which is symbolized by animals living in peace. In Revelation, John hears “every creature in heaven and on earth and under the earth and in the sea, everything in the universe” giving God “blessing and honor, glory and might, forever and ever” (Revelation 5:13). Finally, John sees “a new heaven and a new earth” (21:1) and the Bible ends with a new garden, complete with “the river of life-giving water” and “the tree of life” (22:1-2).
God shows authentic, primal concern for all animals by directing Noah to take a male and female of every species onto the ark to be saved (see Genesis 7:2-3). Apparently, animals matter and are worth “saving.” After the flood, God makes a covenant, not just with people but with all of creation (stated five times in 9:10-17). How did we miss that? Sadly, if we are self-centered, even if we say the Bible is the “inerrant” word of God, we will hear only what we want to hear! God’s salvation—and every biblical covenant—is clearly a social, historical, and universal concept rather than the merely human and individualistic version of salvation that most of us were taught.
This made Christianity into a largely ineffective religion. The notion of salvation became so guarded and so stingy it was finally not available to the vast majority of humans!
If we believe in a Creator-God, who is still in the act of creating this universe, how can we pretend to be interested in God but not interested in what God is doing, in what (presumably) God is interested in?
St. Thomas Aquinas (1225-1274) stated, “The immense diversity and pluriformity of this creation more perfectly represents God than any one creature alone or by itself.”  However, most Christians thought humans were the only creatures that God cared about, and all else—animals, plants, light, water, soil, minerals—was just “food” for our own sustenance and enjoyment.
.. God created millions of creatures for millions of years before Homo sapiens came along. Many of these beings are too tiny for us to see or have yet to be discovered; some have seemingly no benefit to human life; and many, like the dinosaurs, lived and died long before we did. Why did they even exist? A number of the Psalms say that creation exists simply to reflect and give glory to God (e.g., Psalm 104).
