Canon 671

1. Catholic ministers licitly administer the sacraments only to

Catholic Christian faithful, who, likewise, licitly receive the

sacraments only from Catholic ministers. 2. If necessity requires it or genuine spiritual advantage suggests it and provided

that the danger of error or indifferentism is avoided, it is permitted for Catholic Christian faithful, for whom it is physically

or morally impossible to approach a Catholic minister, to receive

the sacraments of penance, the Eucharist and anointing of the

sick from non-Catholic ministers, in whose Churches these sacraments are valid. 3. Likewise Catholic ministers licitly administer the sacraments of penance, the Eucharist and anointing of

the sick to Christian faithful of Eastern Churches, who do not

have full communion with the Catholic Church, if they ask for

them on their own and are properly disposed. This holds also for

the Christian faithful of other Churches, who according to the

judgment of the Apostolic See, are in the same condition as the

Eastern Churches as far as the sacraments are concerned. 4. If

there is a danger of death or another matter of serious necessity

in the judgment of the eparchial bishop, the synod of bishops of

the patriarchal Church or the council of hierarchs, Catholic ministers licitly administer the same sacraments also to other

Christians not having full communion with the Catholic Church,

who cannot approach the ministers of their own ecclesial communities and who request them on their own, provided they manifest

a faith consonant with that of the Catholic Church concerning

these sacraments and are rightly disposed. 5. For the cases in

2, 3 and 4, norms of particular law are to be enacted only after consultation with at least the local competent authority of

the non-Catholic Church or ecclesial community concerned.
