LITURGY OF THE CATECHUMENS
Liturgy of the Catechumens: translation
The catechumens can participate in the first part of the liturgy, where readings and sermons are given. However they don't participate in the liturgy of the believers.
Eucharistic service is comprised of two distinct, inseparable, and complementary sections: the Liturgy of the Catechumens* and that of the believer.
