So she insists she believes the word says the world is spherical but that there is a dome in the sky. I think she got bored halfway through the video after they stopped talking about the stuff from the bible. I see that the firmament is real but as someone who was raised catholic I assumed all religions agreed that it was a metaphysical barrier between heaven and earth. After reading through the comments here I feel like she probably got this from YouTube/ticktock and not from her church.
