Quote from Darwin showing how Evolution is compatible with religion.

Christianity and Evolution

How They are Compatible

  • Catholics believe that God created Earth, and life on it. To understand how this could happen in light of our knowledge of Evolution, we turn to Mariusz Tabaczek, using the writings of St. Thomas Aquinas, to explain.

  • Before this explanation, though, proper definitions must be established. In this context, to create is to bring something into existence from nothing, or ex nihilo.

  • To make is to transform existing matter into new forms. The Catholic perspective on this is that God creates things, and entities that are not God make things.[1]

  • Mariusz Tabaczek argued that God’s creative act was only at the beginning of the universe, where He created everything from nothing. This creative act was not extended over time.

  • After the instantaneous creation of the universe, Tabaczek states that secondary causes under God’s Governance, such as the laws of nature and organisms, were moved by the primary cause, God, toward His final goal of His creation.

  • These secondary causes transformed existing matter into different forms, causing the fuller potential of matter to educe, or be drawn out, from themselves into a different form.

  • In short, God created everything, and secondary causes made new things using God’s creation. Everything made by the secondary causes can still be traced back to their primary cause: God.

  • As such, since God is still the creator of everything, this perspective on the matter is not in contradiction with the Scriptures, but helps one understand how this creation came to be in light of our increasing knowledge of the natural world.[2]

  • It is also important to note that the Catholic Church officially says that Evolution is fully compatible with her teachings, as long as one believes that the human soul did not evolve (CCC§ 159, 283, 284)

  • Thus, if Evolution is truly compatible with Christianity, much of the reasons for Atheism can go away, as Christianity is no longer seen as at odds with science. The History of Atheism

Common Biblical Objections to Evolution

  • Genesis 1:31: “God saw everything that he had made, and indeed, it was very good. And there was evening and there was morning, the sixth day.” [NRSV]. Creationists argue that, “very good,” means that Evolution must be false, because it involves death, which did not occur until the Fall, in Genesis 3. I respond that the death introduced by Adam and Eve is the Second, or Spiritual Death (Revelation 20:14, Romans 5:12, 6:23) not the first, or Physical Death. In addition, physical death is part of God’s planned natural order of life. After all, Psalm 104:21 says, “The young lions roar for their prey, seeking their food from God.” [NRSV]. Adam and Eve’s sin alienated us from God, which is spiritual, not physical, death. Thus, this verse cannot be used against Evolution.

  • Exodus 20:11: “For in six days the Lord made heaven and earth, the sea, and all that is in them, but rested the seventh day; therefore the Lord blessed the sabbath day and consecrated it.” -[NRSV]. Some argue that this verse, and others in Leviticus,  reaffirms Genesis 1’s literalness. But this is an early version of God relating to us by using metaphors (CCC §337), in making His creation similar to our workweek. God’s ultimate relation to us comes later in the Bible, when the Word becomes Flesh in Jesus (יֵשׁוּעַ) Christ (John 1:1-5).

  • In addition, the Pagans in the Ancient Near East had 7-day temple dedication ceremonies, where, on the 7th day of the ceremony, the god of the temple would rest inside the temple [3]. In a similar way, when God, "rested" on the 7th day, He didn't actually rest, as He is all-powerful, but used the imagery of the time to show us that the Cosmos is His temple, and He is present with us today. Later, in Exodus 40:34, this is fulfilled when God's presence joins His people, and, when we celebrate Jesus (יֵשׁוּעַ), the new Sabbath (Mark 2:27-28), we do so with the Eucharist (Mark 14:22-24), where He, who is God, is present with us. For evidence of Jesus (יֵשׁוּעַ)'s real presence in the Eucharist, click here.

  • Mark 10:6/Matthew 19:4: “But from the beginning of creation, ‘God made them male and female.’” [NRSV]. Creationists argue that Jesus (יֵשׁוּעַ) implies that Adam and Eve were made on a literal day 6, which is closer to the beginning than millions of years later. Either way, though, Day 6 is not the beginning, Day 1 is, so Jesus (יֵשׁוּעַ) is likely talking about the creation of Humanity, specifically, not the universe, using similar language in the Genesis 1:27. In addition, the main purpose of this verse is the sanctity of marriage (CCC §1604), not to give scientific information.

Common Theological Objections to Evolution

  • Genesis 1, “yom” means literal day: Some Young Earth Creationists, like Calvin Smith of Answers in Genesis Canada, argue that the Hebrew word for Day, yom, in Genesis 1 means a literal 24 hour day, nothing else. Any other definitions added would distort the meaning of God's word, and, thus, Christianity.[4] I respond that it I say it took me a million years to do something, a year means 365.25 days, nothing more, nothing less. But the overall sentence is metaphorical. See the next page for what Genesis 1 is about.

  • What about Noah’s Flood? In Genesis 6:17, it says, “For my part, I am going to bring a flood of waters on the earth, to destroy from under heaven all flesh in which is the breath of life; everything that is on the earth shall die.” [NRSV] Some argue that the Bible is clear: the whole world, or Planet Earth, flooded. The original Hebrew word for all Earth is whole [kol] and Earth [erets] just mean the general area, not all of planet Earth as we think today, though. After all, Exodus 34:10 says: “He said: I hereby make a covenant. Before all your people I will perform marvels, such as have not been performed in all [kol] the earth [erets] or in any nation…” [NRSV, Hebrew added by myself]. It is evident that this is talking about the local area, as why would the Bible say every nation if they already talked about the whole Planet? [5] Thus, Noah’s flood was likely a local, symbolic event and not a global event. Whenever reading the Bible, it is important to take into account cultural context and literary genres to deduce the full meaning of the text (CCC §109-110).​​​

  • What about Adam and Eve? It clearly says in Genesis 2: 7-25 that they were the first two people, and Pope Pius XII in Humani Generis §37 clearly says that we are from two people (monogenism), not thousands (polygenism) as Evolution says. I argue that a person is a Homo sapien with a human soul. So, humanity started with 10,000 Homo sapiens [6], evolving into existence, then Adam and Eve got two souls, making them the first people, for God’s demonstration that He knew would be written in Genesis. Then they sinned, and God split their soul like a family tree, and gave a bad soul to every Homo sapien. Therefore, there is biological polygenism, but spiritual monogenism. [7] We, humans, share Adam and Eve’s sin and fall in spirit, not necessarily genetics. While this is unsettled with the Catholic Church, this idea does not contradict core Church doctrines. [7]

  • Why would God put the 7-day creation in Genesis if it is so confusing to people? I respond: Matthew 16: 18-19 says, “And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” [NRSV] Jesus (יֵשׁוּעַ) founded the Roman Catholic Church, to guide the Christians to the truth, and settle disputes such as this through their God-guided interpretations. There are hundreds of thousands of words in the Bible, and many ways to interpret it. And, this church affirms that faith, science, and reason never contradict (CCC §159). The Catholic Church is guided by God to find the right interpretation. Thus, the peace of God be with you always.

  • Why interpret the Bible using knowledge from outside the Bible? God is the source of all truth (CCC §2465), and, thus, any truth, including that from correctly-done science, cannot contradict God, as the truth never contradicts itself (CCC §159). It is also well-known that Evolution is, for the most part, a correct theory, and denying the truth can never work in the long-term, as God asks all of His people to live in truth. Thus, these beliefs must be reconciled together, which is why one must interpret the Bible like this. Evidence for Evolution
