The state or period of being a catechumen; the institution or system of instruction for catechumens in a church.
From 'catechumen' plus the noun-forming suffix '-ate' (a state or office), creating an abstract noun describing the status or institution.
The catechumenate as an institution shows how the early church was actually quite sophisticated about education—it had a structured curriculum, progression levels, and even a time-based system, making it one of the first formalized educational institutions in Western history.
