"it is not Catholic teaching that God is a murdering rapist. " Sure it is, God drowned them all in a flood, it says so in CHAPTER ONE! And they teach that as well...
" All I am saying that understanding the author's original intent and the people the author was addressing adds to and broadens any perspective". So what was the reason to use a story about a murdering raping god?
I've already gone over this, but I will try again. The original author and his audience come from a perspective that a good, just, and loving God created a good world. They saw humans as making an evil mess of it all. Where was goodness? Where was justice? Where was love? Bible literalists see God as sending a flood and starting over.
I've read Jewish commentary that points out several things: First, the Bible states that after God separated land and water, the entire globe was never again covered with water. They see in the actual account that mountains could not be seen through the rain, but after the rain stopped, mountains could be seen again.
Another commentary is that God is the same yesterday, today, and tomorrow. Thus, either every natural disaster today is designed and sent by God to a precise place and purpose, or yesterday's Great Flood was also a natural disaster. What happens after natural disasters? People take stock of themselves and what they have been doing. The account of The Great Flood was written with this hindsight.
Next, what is
your experience of God? Did God murder one of your family members? Did He rape another?
Look, you are asking me to sum up decades of study in an online post. How many decades of study did you undertake before reaching your conclusion? Or, did you read the story once, decide you had perfect understanding of what happened thousands of years ago, and jump to a conclusion to fit a personal agenda? That is okay. Some feel they need a good reason to turn from any childhood teaching. In that way I feel we may be quite similar. I chose one direction, you chose another.
