Laudatur Iesus Christus.
Dear Applefan:
Here’s a passage on the Feast of the Transfiguration, from the Catholic Encyclopedia:
The Latin Church was slow in adopting this feast; it is not mentioned before 850 (Martyrology of Wandelbert, Gavanti, “Thesaurus Liturg.”, II, August);
it was adopted in the liturgy about the tenth century in many dioceses, and was celebrated mostly on 6 August; in Gaul and England, 27 July; at Meissen, 17 March; at Halberstadt, 3 September, etc. In 1456 Callixtus III extended the feast to the Universal Church in memory of the victory gained by Hunyady at Belgrade over the Turks, 6 August, 1456. Callixtus himself composed the Office. It is the titular feast of the Lateran Basilica at Rome; as such it was raised to a double second class for the Universal Church, 1 Nov., 1911. (boldface added) (
newadvent.org/cathen/15019b.htm)
It seems that the feast was already celebrated on the 6th of August. Why Pope Callixtus extended that feast rather than instituting or extending another isn’t mentioned. The concurrence of the reception of the news and an already widely celebrated feast may be reason enough.
Celebrating on this day seems theologically poignant. God was already incarnate; at the Transfiguration, His divinity was clearly revealed. Similarly, the battle against the Turks had already been won; on the 6th of August, the victory was clearly revealed.
Gratia tibi et pax.
