Christ was sold by Judas on a Wednesday and died on a Friday. On Fridays then, Orthodox do not even eat fish.
I am not an example. It is Wednesday, and I had butter on the bread this breakfast. Dairy, egg and meat are also non-fasting foods. Though next week, if I got it right on internet, I can eat dairy but no meat all week days till Sunday. The Monday after begins Great Lent.
Our Lady in Fatima appeared last time on 1917 October 13 Gregorian Calendar - the Vigil of October 14 Gregorian/1 Julian Calendar (13 days of difference in 20th and 21st Cs) which is the Orthodox Feast Protection of the Theotokos. The event celebrated is prelude to the conversion of the Slavs. That appearance was the vigil of the last time the Czar St Nikolai II celebrated that feast. One of her requests in Fatima was to fast on Wednesdays and Fridays. I e like the Orthodox. And, for that matter, like the Uniates.
PS: Shellfish does not count as fish in this context.
