In ecclesiology, a catechumen (; 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, Lutheran, Methodist, Orthodox, Reformed/Presbyterian, and Roman Catholic Christians. 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."
