Minkymurph, I apologize for misunderstanding you. With that, I am curious where you get the idea that the Catholic Church teaches that Genesis 1-3 are the genre “myth”. The PBC listing above clearly states that Genesis 1-3 are historical (history) accounts that use allegory and symbols. The Church teaches that the genre is “history”, not “myth”. The thought that Genesis 1-3 is “myth” is purely modernistic and has no root in Sacred Tradition.
No need to apologize. I’m not as sensitive as my words may suggest.
I went into this in another post - 127. However, further and more specific clarification is warranted.
Firstly, I do not have the idea the Catholic Church teaches that Genesis 1 - 3 are the genre ‘myth.’ Neither am I using the term ‘myth’ in relation to the Genesis account in a contemporary context. To explain, the term ‘myth’ is often interpreted and used today in a derogatory sense - to denote a story of piece of writing is nothing more than a figment of the author’s imagination and should be taken with a pinch of salt. I’m not using the term ‘myth’ in that context. To explain further, language dramatically changes over centuries and a term used in the past could have a completely different meaning today. To illustrate, in the past being ‘gay’ meant being happy and wanting to sing with joy. I’m sure I don’t need to explain it is used in a very different context today!

To illustrate further, imagine going back in a time machine and trying to explain what an ‘e-mail’ or ‘ipod’ is, or translate them into an ancient language.
The term ‘myth narrative’ is used to describe a particular literary form, or style of writing. Myth narratives were common in the Ancient Near East and were an essential element of life in the Ancient Near East. There no institutions of learning, no religious institutions, no courts, no human rights legislation and no tv or internet. Therefore, morals and values, religious beliefs, social function, the history of the tribe or people and many other things, were preserved and passed to future generations through the telling and re-telling of ‘myth narratives.’ They also served a social function as nomadic people’s gathered around camp fires to hear these stories. ‘Story’ or ‘story telling’ does not mean pure fiction. It’s a style of teaching. I stand to be corrected but myth narratives may also be specific to a particular era. Meaning, is gives us a clue as to how old a particular piece of writing is and in what time period it may have been written which is a clue to it’s source.
The term ‘myth narrative’ in a literary sense means - ‘a traditional story, esp. one concerning the early history of a people or explaining some natural or social phenomenon, and typically involving supernatural beings or events.’ It’s more than possible that the Genesis story was handed down orally from generation to generation before it was ever written down. Therefore, it is a traditional story. It is written in a narrative style; no use of personal nouns, then God did this, then God did that, then God said, this happened, then that happened - the author in effect is ‘narrating.’ The content
is historical - the history of creation, an explanation of the origins of the human race and the Fall, but it’s being recounted in a certain style, (not a modern academic style) and from a theological perspective rather Creation is a both a natural and supernatural event - God, the spirit of God is involved, a serpent or snake speaks. It has a social aspect - Adam’s intimate relationship with God and Eve and consequent breakdown of the relationships. Therefore, because of the literary structure and content, Genesis 1 - 3 has been identified as a ‘myth narrative’ by biblical scholars. This school of thought has been around from the 18th century, so I don’t know if it can be termed ‘modernistic,’ but I suppose it depends on your point of view.
