HEAVENLY Father, who before the passion of your only Son revealed his truly glory upon the holy mountain to chosen witnesses: Grant that we, your servants, beholding the light of his transfigured face by faith, may be strengthened to bear the cross, and be changed into his likeness from glory to glory; through Jesus Christ our Lord.
Exodus 24:12-35; Psalm 84:1-7; 1 John 3:1-3; Mark 9:2-7
The event described in the Gospel is the commemoration of today’s holiday. It is a similar event to various moments in the Old Testament, such as in today’s reading. But this changing of Jesus’ appearance (his “transfiguration”) occurred shortly before he went to Jerusalem to die, which is why the Collect asks for strength for us also to bear the cross, in addition to asking for us to be changed in to Christ’s likeness, which the Epistle teaches about.
