The noun ‘Catechism’ (meaning ‘Instruction’) is derived from the Greek verb kat-eechein (meaning: ‘to echo thoroughly’). The verb is found in the New Testament, at: Luke 1:4; Acts 18:25 & 21:21 & 21:24; Romans 2:18; First Corinthians 14:19; Galatians 6:6; and Hebrews 10:23. There, it refers: to Hebraic instruction from God’s Law; to the Christian catechizing of Theophilus and Apollos; to good educating by the Apostle Paul; to the training of others in the Church; to in- doctrin-ating in and being in-doctrin-ated into the teachings of Christianity; and to “hold[ing] fast the ‘Profession of our Faith’” made on becoming Communicants of the Church.
