Canon 208

1. An eparchial bishop exercising authority within the territorial boundaries of a patriarchal Church, within five years of

his enthronement, is to make a visit to Rome along with the patriarch, insofar as this can be done, so that he may venerate the

tombs of blessed apostles Peter and Paul and appear before the

successor of Saint Peter in the primacy over the entire Church.

2. Other eparchial bishops are to make the visitation to Rome

personally every five years or, if legitimately impeded, through

another; if it is a case of bishops of a patriarchal Church, it

is desirable that at least some time it be done with the patriarch.
