also, a brief chronology of the events from an Orthodox perspective would be helpful (ideally with some sources), for example some would say:
last supper: eve of 14th (thurs)
death: 3 pm on 14th (fri)
resurrection: Sunday morning
This, as far as I'm aware.
This is the chronology of St. John the Theologian, as laid out in his Gospel. The Synoptic Evangelists do
record a different chronology. How do we reconcile them? We don't. It doesn't matter. St. John is making a point by theologically connecting the Passion of our Lord with the slaying of the lamb in the Temple at Yom Kippur, for he is "...the Lamb slain from the foundation of the world" (Apocalypse of St. John the Theologian, ch. 13, v. 8http://)
