Historical context

What was happening when this word was written?

Roman-Occupied Judea (c. 4 BC-AD 30)

John wrote for an audience familiar with both Jewish Scripture and Greek philosophy. The logos — the Word — was a term Greek philosophers used for the rational principle underlying the universe. John takes that concept and says: that logos became a person and lived among us. Crucifixion was the Roman execution method designed to maximize public humiliation, reserved for slaves and rebels.

The people who first heard this word were not reading a book — they were living through empires, oppression, exile, and covenant. Every word carried the weight of that reality. Understanding it changes how you read Scripture.
