EPISTLE

2 Peter 1: 16-19  

Lesson from the Epistle of blessed

Peter the Apostle

Dearly beloved, We have not followed cunningly

devised fables, when we made known to you the

power and presence of Our Lord Jesus Christ; but

having been made eyewitnesses of His majesty.

For He received from God the Father honor and

glory: this voice coming down to Him from the

excellent glory, This is My beloved Son in

Whom I am well pleased, hear ye Him. And this

voice we heard brought from Heaven, when we were

with Him in the holy mount. And we have the more firm

prophetical word, where unto you do well to attend,

as to a light that shineth in a dark place, until the

day dawn, and the day-star arise in your hearts.

GRADUAL 

Psalm 44: 3, 2

Thou art beautiful above the sons of men: grace

is poured abroad in Thy lips. My heart hath uttered

a good word. I speak my works to the King.

Alleluia 

Wis. 7: 26

Alleluia, alleluia. He is the brightness of eternal light,

the unspotted mirror, and the image of His goodness. Alleluia.

GOSPEL 

Matthew 17: 9

The continuation of the holy Gospel according to Matthew.

At that time, Jesus took Peter, and James, and John

his brother, and bringing them up into a high mountain

apart: and He was transfigured before them. And His face

did shine as the sun, and His garments became white as snow.

And behold, there appeared to them Moses and Elias talking

with Him. And Peter answering, said to Jesus,

Lord, it is good for us to be here; if Thou wilt,

let us make here three tabernacles, one for Thee, a

nd one for Moses, and one for Elias. And as he was

yet speaking, behold a bright cloud overshadowed them;

and lo, a voice out of the cloud, saying

“This is My beloved Son in Whom I am well pleased,

hear ye Him.” And the disciples hearing, fell upon their

face; and were very much afraid: and Jesus came and

touched them, and said to them, “Arise, and fear not.”

And they lifting up their eyes saw no one, but only Jesus.

And as they came down from the mountain, Jesus charged

them, saying, “Tell the vision to no man, till the

Son of man be risen from the dead.”

Glory and wealth are in His house: and His justice

It is truly meet and just, right and for our salvation, that we

should at all times and in all places, give thanks unto Thee,

O holy Lord, Father almighty, everlasting God: for through

Thy glory hath shone upon the eyes of our mind, so that

while we acknowledge God in visible form, we may be

through Him be drawn to the love of things invisible.

And therefore with Angels and Archangels, with Thrones

and Dóminations, and with all the hosts of the heavenly army,

we sing the hymn of Thy glory, evermore saying:

SANCTUS, SANCTUS, SANCTUS

Dominus Deus Sabaoth. Pleni sunt coeli et terra gloria Tua.

Hosanna in excelsis.  Benedictus qui venit in nomine Domini.

Hosanna in excelsis.
