I find at James 1:27 three (3) activities: besides caring for (1) orphans and (2) widows, one must also keep free from (3) being spotted by the world (world alienated from God ).So is 'pure' religion limited to only these two activities? A biblical literalist would have to say 'yes.'
How Jesus and his followers kept separate, unspotted, was to remain neutral in world affairs.
They did Not even get involved in the issues of the day between the Jews and Romans but always neutral.
