The Office hymns in the English Hymnal are not great for this feast; the traditional Vespers hymn is good, although I’m not sure whose translation this is:
All ye who seek for Jesus, raise
your eyes above, and upward gaze:
there may ye see the wondrous sign
of never-ending glory shine.
Behold him in celestial rays
who never knoweth end of days;
exalted, infinite, sublime;
older than heav’n or hell or time.
This is the Gentiles’ King and Lord;
the Prince by Judah’s race adored,
promised to Abraham of yore
and to his seed for evermore.
To him the prophets testify;
and that same witness from on high,
the Father seals by his decree:
‘Hear and believe my Son’, saith he.
All glory, Lord, to thee we pay,
transfigured on the mount today;
all glory as is ever meet,
to Father and to Paraclete
I think the Lauds hymn is especially lovely:
O love of Jesus, sweet and dear,When to the heart thou dost appear,away its clouds and darkness roll,And sweetness overflows the soul.How happy he who feels thy light,Thou sharer of the Father’s might,True radiance of our native land,Surpassing all we understand.Thou brightness of the Father’s throne,Goodness that never can be known,The fullness of thy love impartBy thy true Presence in the heart.All glory, Lord, to thee we pay,Transfigured on the mount to-day;All glory, as is ever meet,To Father and to Paraclete.
There is also the following text from The Monastic Diurnal Revised (1989):
O wondrous type! O vision fair
of glory that the Church may share,
which Christ upon the mountain shows,
where brighter than the sun he glows!The law and prophets there have place,the chosen witnesses of grace;the Father’s voice from our the cloudproclaims his only Son aloud.With shining face and bright array,Christ deigns to manifest todaywhat glory shall be theirs abovewho joy in God with perfect love.And faithful hearts are raised on highby this great vision’s mystery;for which in joyful strains we raisethe voice of prayer, the hymns of praise.O Father, with the eternal Son,and Holy Spirit, ever One,vouchsafe to bring us by thy graceto see thy glory face to face.
Hymns for Prayer and Praise has two very good hymns one from Stanbrook and the other from Mount Saint Bernard. The Church of Scotland has an interesting text at number 353 of its Church Hymnary fourth edition which makes the connection with the dropping of the atomic bomb on Hiroshima on this day in 1945, the hymn is by Carl P. Daw Jr, and the second verse begins:
Bright the cloud but dark the glorywrought by human enterprise,opening wide with awful terrorstark new worlds before our eyes.
The glory that is ours this dayis shed by neither moon nor sun:the dazzling splendour we beholdshines forth from Christ, God’s cherished one.Each planet, galaxy and starwithin the spectrum of this lightfinds her its origin and end,this day revealed on Tabor’s height.And we, so vulnerable and smallare shown what we cannot conceive:that we mere vessels made of clayand glorious beyond belief!Yet millions massacred this dayreduce to ash all human ride:the burning sun we dropped demandswe ponder why it is Christ died.Hiroshima’s bright blinding cloudmust ever haunt us with its glare:we chose that day to be as gods;we shadowed all the earth with fear.Earth now is clouded by a light,unknown to Peter, James and John:could Tabor pointing to the Crossconceive the suff’ring of that bomb?O Christ, have pity on our racewhich parodies your healing light:Come, Abba, Breath and Word enfleshedtransfigure and restre our sight.
IUpon Mount Tabor, all alone,Christ draws these three apostles near.His face blinds like the summer sun;his clothes, like winter’s snow, appear.Then suddenly the cloud is gone:He’s there, the Jesus that they know:familiar friend, close at their side,he tells all he must undergo.Both love and fear have here embraced;both point ahead to Easter morn.the vision that they here have sharedwill be transparent wit that dawn.O Christ, come fashion us anewto find outfaces in your face;With wonder may our hearts expand,till filled with Tabor’s dazzling grace.IIO sole begotten Word of Godaddressed to us within our flesh:your glory freely laid asidethis day your Abba manifests.Transfigured on Mount Tabor’s heighta new creation was unveiled:yet you alone could show us allthis path to glory would entail.Wrapped wond’rously in radiant lightyou gave your chosen ones foretasteof all you would accomplish whenyour cross-flung arm the world embraced.Your brilliance Lord emblazons earthand so betrays our shadowed hearts:yet inextinguishable withinthere burns the Image God imparts!O Lord how good that we are heretogether gathered in this place!Your promised presence dwells in usand touches all who seek your face.O loving Abba of the world;O Christ resplendent and blaze;O spirit now transfig’ring us:may we ourselves be now your praise.
