The Feast of the Trans­fig­u­ra­tion  is cel­e­brat­ed each year on August 6 (o.s.). The feast com­mem­o­rates the trans­fig­u­ra­tion or meta­mor­pho­sis of Christ on Mount Tabor, when our Lord appeared in His divine glo­ry before the Apos­tles Peter, James, and John short­ly before his sav­ing Passion.

Let us be freed from these by the illu­mi­na­tion and knowl­edge of the incor­po­re­al and ever-exist­ing Light of our Sav­ior trans­fig­ured on Tabor, in His Glo­ry, and of His Father from all eter­ni­ty, and His Life-Cre­at­ing Spir­it, Whom are One Radi­ance, One God­head, and Glo­ry, and King­dom, and Pow­er now and ever and unto ages of ages. Amen.1
