“Nope. She’s human, but without sin. This whole can of worms sets up blasphemous attacks on Catholic beliefs, but also those of the Eastern Orthodox, who hold the same belief.”
You deny Mary is divine, but then contend that questions about her constitute blasphemy. Blasphemy is criticism of a faith’s beliefs about divinity so criticisms or questions about Mary should not be considered blasphemy unless you consider Mary divine. I’m confused.
From blasphemy:
2: "irreverence toward something considered sacred or inviolable"
I'm using that second definition.
