Do you have favorite Canons from the Code of Canon Law? There are a few that I really like. And this is one of them.
Can. 844 § 4. If the danger of death is present or if, in the judgment of the diocesan bishop or conference of bishops, some other grave necessity urges it, Catholic ministers administer these same sacraments licitly also to other Christians not having full communion with the Catholic Church, who cannot approach a minister of their own community and who seek such on their own accord, provided that they manifest Catholic faith in respect to these sacraments and are properly disposed.
And here it is, reportedly being applied in the service of a Methodist seeking communion. Via the Deacon’s Bench…Report: Methodist Mandela received communion from Catholic priest while in prison.
