Nomina sacra means "Sacred names" in Latin, and can be used to refer to traditions of abbreviated writing of several frequently occurring divine names or titles in early Greek language Holy Scripture. The Bruce Metzger's book Manuscripts of the Greek Bible lists 15 such expressions from Greek papyri: the Greek counterparts of God, Lord, Jesus, Christ, Son, Spirit, David, cross, Mary, Father, Israel, Savior, Man Jerusalem, and Heaven. The contractions were written with overlines.
