Euangelion is the Greek word your English Bible turns into "gospel," and the Hebrew underneath it is besorah. But the Greek carries something of its own that is worth knowing, because of who was already using the word when the Brit Chadashah picked it up.

Euangelion was Roman imperial vocabulary. The calendar inscription from Priene, cut in 9 BC to honor Augustus, says the birthday of the god Augustus was for the world the beginning of the good news, the euangelia, that came by reason of him. That is the register the word lived in: the announcement of an emperor's birth, an accession, a victory in the field. It was the language of the state telling you who your lord was and that the good times had begun.

So when Mark opens with the euangelion of Yeshua Mashiach, and when Sha'ul says he is not ashamed of the euangelion, they are not reaching for a mild religious term. They are taking the empire's own proclamation word and pointing it at a different King. The claim is not that a new religion has arrived. The claim is that Caesar is not the one whose reign was announced. Read that way, the word carries the same weight as the Hebrew it renders. Isaiah's herald cries that your God reigns. The Greek says it in the vocabulary Rome had trained the whole Mediterranean to recognize. What it never meant, in either language, was a plan of personal salvation summarized in four points. It meant a throne had been taken.
