Praying "Suffrages" and "Phos Hilarion"

I'm praying the daily office again. I know, it's a long story. Since I've been back into my old habit, I have found two prayers to be particularly good. The first is called "Suffrages" and it goes like this:

Show us your mercy, O Lord;

   And grant us your salvation.

Clothe your ministers with righteousness;

   Let your people sing with joy.

Give peace, O Lord, in all the world;

   For only in you can we live in safety.

Lord, keep this nation under your care;

   And guide us in the way of justice and truth.

Let your way be known upon earth;

   Your saving health among all nations.

Let not the needy, O Lord, be forgotten;

   Nor the hope of the poor be taken away.

Create in us clean hearts, O God;

   And sustain us with your Holy Spirit.

The second is called "Phos Hilarion" (O Gracious Light) and it goes like this:

O gracious light,

pure brightness of the everliving Father in heaven,

O Jesus Christ, holy and blessed!

Now as we come to the setting of the sun,

and our eyes behold the vesper light,

we sing your praises, O God: Father, Son, and Holy Spirit.

You are worthy at all times to be praised by happy voices,

O Son of God, O Giver of Life,

and to be glorified through all the worlds.

Glory to the Father, and to the Son, and to the Holy Spirit:

as it was in the beginning, is now, and will be for ever. Amen.
