Greek cases are the backbone of sentence structure, each one signaling a distinct role. The nominative marks the subject or equates it with something (ὁ θεός φῶς ἐστιν), while the genitive shows possession, origin, or relationship (τοῦ διδασκάλου, Ἰησοῦ Χριστοῦ). The dative handles indirect objects, instruments, and locations (τῷ παιδίῳ, ἐν τῇ πόλει), and the accusative targets direct objects or measures of time and space (τὸν ἄνδρα, τρεῖς ἡμέρας). The vocative calls out directly—κύριε, ἄνθρωπε. These endings do more than mark grammar; they shape meaning, reveal emphasis, and unlock interpretive depth, especially in texts where theology and syntax intertwine.
