Kerygma
Kerygma (from Ancient Greek: κήρυγμα, kḗrygma) is a Greek word used in the New Testament for 'proclamation' (see Luke 4:18-19, Romans 10:14, Gospel of Matthew 3:1). It is related to the Greek verb κηρύσσω (kērússō), literally meaning 'to cry or proclaim as a herald' and being used in the sense of 'to proclaim, announce, preach'.
