Holy Wednesday has no founder and no establishing document. It is simply the Wednesday of Holy Week, and the earliest detailed account of how it was kept comes from the pilgrim Egeria, who recorded the practice of the church in Jerusalem in the late fourth century.
What a pilgrim saw in Jerusalem
Egeria was a pilgrim, and almost everything else about her is guesswork. What survives is her account of the church in Jerusalem, and in it the Wednesday of Holy Week is a service held after dark. A priest read out the passage in which Judas Iscariot went to the authorities and settled his price.
It is the reaction she recorded most exactly. When the passage had been read, Egeria wrote, there is such a moaning and groaning of all the people that no one can help being moved to tears at that hour. Nobody had instituted the day; the earliest record of it is a record of people weeping.
