Catechesis refers to education in the teachings and practices of Christianity. Formal catechesis (e.g. classes, group meetings, or one-on-one instruction) normally preceeds the confirmation of youth in Lutheran churches, the reception of new members to a congregation (especially from non-Lutheran churches), and the conversion of young people or adults to Christianity. However, in many churches, catechesis is also a life-long process, in which Christians intentionally deepen their understanding of the Way of Jesus through continuous learning and doing.
