Trinity Sunday

Collect
Almighty and everlasting God,
you have given us your servants grace,
by the confession of a true faith,
to acknowledge the glory of the eternal Trinity
and in the power of the divine majesty to worship the Unity:
keep us steadfast in this faith,
that we may evermore be defended from all adversities;
through Jesus Christ your Son our Lord,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.  Amen.

Isaiah 6.1–8
In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lofty; and the hem of his robe filled the temple. Seraphs were in attendance above him; each had six wings: with two they covered their faces, and with two they covered their feet, and with two they flew. And one called to another and said:
Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory.’
The pivots on the thresholds shook at the voices of those who called, and the house filled with smoke. And I said: ‘Woe is me! I am lost, for I am a man of unclean lips, and I live among a people of unclean lips; yet my eyes have seen the King, the Lord of hosts!’
 Then one of the seraphs flew to me, holding a live coal that had been taken from the altar with a pair of tongs. The seraph touched my mouth with it and said: ‘Now that this has touched your lips, your guilt has departed and your sin is blotted out.’ Then I heard the voice of the Lord saying, ‘Whom shall I send, and who will go for us?’ And I said, ‘Here am I; send me!’

Psalm 29
    Ascribe to the Lord, you powers of heaven, 
   ascribe to the Lord glory and strength.
    Ascribe to the Lord the honour due to his name; 
   worship the Lord in the beauty of holiness.
    The voice of the Lord is upon the waters;
      the God of glory thunders; 
   the Lord is upon the mighty waters.
    The voice of the Lord is mighty in operation; 
   the voice of the Lord is a glorious voice.
    The voice of the Lord breaks the cedar trees; 
   the Lord breaks the cedars of Lebanon;
    He makes Lebanon skip like a calf 
   and Sirion like a young wild ox.
    The voice of the Lord splits the flash of lightning;
      the voice of the Lord shakes the wilderness; 
   the Lord shakes the wilderness of Kadesh.
    The voice of the Lord makes the oak trees writhe
      and strips the forests bare; 
   in his temple all cry, ‘Glory!’
    The Lord sits enthroned above the water flood; 
   the Lord sits enthroned as king for evermore.
      The Lord shall give strength to his people; 
   the Lord shall give his people the blessing of peace.
