Britannica: ...It is not known when the festival was first celebrated, but it was kept in Jerusalem as early as the 7th century and in most parts of the Byzantine Empire by the 9th century. It was gradually introduced into the Western Church, and its observance was fixed as August 6 by Pope Calixtus III in 1457 as a thank offering for the victory over the Turks at Belgrade on that day in 1456....
The Gospel is also used on Ember Sat in Lent and Sunday Lent II.
