Many of the books and letters that make up the bible were written anonymously. And some are complete forgeries.
The people of Jesus’s day, including Jesus himself, spoke Aramaic. But the bible was written in Greek and translated from Greek to other languages. Things always get lost in translation.
The first Gospel wasn’t written until approximately 30 to 40 years after the death of Jesus (the others even later). Meaning that the stories about him were passed on through oral tradition for an entire generation before anyone wrote them down.
There are plenty of reasons to wrestle with the bible (the above are just a few). Questioning it doesn’t mean a lack of faith. It means you’re learning.
