 For historical reasons a number of the parishes in the diocese celebrate the liturgy but according to the Ambrosian Rite, rather than according to the Roman Rite.They are the vicariate of Calolzio-Caprino (Calolziocorte, Caprino Bergamasco, Carenno, Cisano Bergamasco, Erve, Monte Marenzo, Torre de' Busi and Vercurago) and the parishes of Averara, Brumano, Cassiglio, Cusio, Ornica, Santa Brigida, Taleggio, Valtorta and Vedeseta.The diocese maintains strong relations with the Roman Catholic Archdiocese of Cochabamba in Bolivia.
