A community of nuns from the congregation "Auxiliares parroquiales de Christ Sacerdote" are responsible for the sacristy of the Cathedral. They are also in charge of the training and organization of the altar boys and they collaborate in the liturgy and in acts of piety.
This is a congregation of Pontifical Right and was founded in 1927 by the servant of God José Pío Gurruchaga. A process for his beatification is currently underway. The community of the Cathedral of Barcelona was established in 1954.
