Four years after writing "my vision is that Wikipedia should not say E is a fool when all it can really say is that D has called E a fool" Lima has taken the opposite opinion in the same article.  The preferred edit is that church teaching places the origin of the Eucharist in last supper, and cites the Catholic catechism, and Orthodox Encyclopedia and an Anglican Bishop.  Reading the footnotes, one discovers the cited passages to not support that thesis.  And instead of reproducing quotes faithfully, or arguing for some exception to a policy which requires verifiability, the article is rerverted to the point of view of the editors,  without even selective quotation.

On the positive side, I'm learning a lot about Eucharist-not from this Wikipedia article, I have to say, as much as running down footnotes,

I never knew the Eucharist was announced before the Last Supper until I read in the Catholic catechism.  That tidbit doesn't appear in any Wikipedia article I read.

The Last Supper is the institution of the Eucharist to Catholic, not the origin, according to the Catholic catechism cited here from 1993.

Yet you couldn't tell it from our little article
