Fast forward to the New Testament, which was written mainly in Koine Greek, the common language of the Mediterranean region at the time. It's like the ancient equivalent of English being the global language today - everyone spoke it, from merchants to philosophers. And, fun fact, the New Testament is actually a collection of letters, stories, and sermons written by different authors, kind of like a spiritual blog!
The reason for the language switch from Hebrew to Greek is largely due to the fact that the Roman Empire was in charge, and Greek was the language of the empire. It's like when you're at a café and everyone starts speaking in a different language - you gotta adapt, right? So, the early Christian writers used Greek to spread their message to a wider audience.
