Canon 199

1. The eparchial bishop, as the moderator, promoter and guardian of the entire liturgical life in the eparchy committed to

him, must be vigilant that it be fostered as much as possible and

ordered according to the prescriptions and legitimate customs of

his own Church sui iuris. 2. The eparchial bishop is to see to

it that in his own cathedral at least part of the divine praises

are celebrated, even daily, according to the lawful customs of

his own Church sui iuris; also, in any parish if possible, the

divine praises are to be celebrated on Sundays, feast days, principal solemnities and their vigils. 3. The eparchial bishop is

to preside frequently at the divine praises in the cathedral or

other church, especially on holy days of obligation, and on other

solemnities in which a sizeable part of the people participate.
