If there is a danger of death or if, in the judgement of the diocesan bishop or of the episcopal conference, there is some other grave and pressing need, Catholic ministers may lawfully administer these same sacraments [confession, the Eucharist, and the anointing of the sick] to other Christians not in full communion with the Catholic Church, who cannot approach a minister of their own community and who spontaneously ask for them, provided that they demonstrate the Catholic faith in respect of these sacraments and are properly disposed (canon 844 §4).
