I think that fundamentalist views come from a lack of knowledge of the religion itself. Seems kinda suspect that your pastor went to seminary and learned that historically the Jews didn’t come from Egypt but the land of Canaan, had zero cultural exchange with Egypt, and did the same things they called the canaanites evil for (looking at you sacrificing your daughter Jepthah), but with a straight face will preach the exodus and plagues to an ignorant congregation.
I was so Christian it became incompatible with modern Christianity, and I’m not the only one.
The truth doesn’t fear the light, or being asked questions and cross examined, and Christian’s fear nothing greater to the point they have to pretend the ultimate evil big bad is creating the questions, and not the lies they told us for centuries.
