Iam lucis orto sidere

Now doth the sun ascend the sky,
And wake creation with its ray;
Keep us from sin, O Lord most high!
Through all the actions of the day.

Curb Thou for us th’ unruly tongue;
Teach us the way of peace to prize;
And close our eyes against the throng
Of earth’s absorbing vanities.

Oh, may our hearts be pure within!
No cherish’d madness vex the soul!
May abstinence the flesh restrain,
And its rebellious pride controul.

So when the evening stars appear,
And in their train the darkness bring;
May we, O Lord, with conscience clear,
Our praise to thy pure glory sing.

To God the Father glory be,
And to his sole-begotten Son;
The same, O holy Ghost, to Thee,
While everlasting ages run.
