In ecclesiology, a catechumen (/ˌkætᵻˈkjuːmən, -mɛn/; via Latin catechumenus from Greek κατηχούμενος katēkhoumenos, “one being instructed”, from κατά kata, “down” and ἦχος ēkhos, “sound”) is a person receiving instruction from a catechist in the principles of the Christian religion with a view to baptism. The title and practice is most often used by Anglican,[1] Lutheran,[2] Methodist,[3] Orthodox, Reformed/Presbyterian,[4] and Roman Catholic Christians.[4] Ecumenical organisations such as the North American Association for the Catechumenate are helping to, across several denominations, “shape ministries with adult seekers involving an extended time of faith formation and a meaningful experience of adult baptism at Easter.”[5][6]
