Canon 678

1. In the territory of another it is not licit for anyone to

administer baptism without the required permission; this permission cannot be denied by a pastor of a different Church sui iuris

to a priest of a Church sui iuris in which the person to be baptized is to be enrolled. 2. In places where there are not a

few Christian faithful lacking a pastor of the Church sui iuris

in which they are enrolled, the eparchial bishop should designate

a priest of that Church, if it is possible, who should administer

baptism.
