Made a saint by the Christian church, or treated as if someone is a saint because they're extremely good or virtuous.
From 'saint' (Old English 'sanct' from Latin 'sanctus' meaning holy), with the suffix '-ed' meaning made or having become. The metaphorical sense of treating someone as saintly emerged in the 17th century.
We 'saint' people even without official church approval—calling someone a 'saint' for their patience or kindness is a quick way our language lets us acknowledge extraordinary virtue, which shows how much we still rely on religious vocabulary for describing moral extremes.
