In the ancient Church, a catechumen (pronounced "cat-a-cumin") was an adult being prepared for Christian initiation in a process called the catechumenate.
Catechumenal ministries are ministries of formation that are inspired by the ancient catechumenate.
Like the catechumenate, they are an annual process of learning integrated with the liturgical year, and culminating with the celebration of Easter.
Like the catechumenate, their goal is to equip us for baptismal living: being able to live our baptismal vows faithfully.
Catechumenal ministries are for everyone, both those preparing for baptism and those already baptized.
