Fr. Jon, I posted this reply the day you first uploaded it. I must have forgotten to hit Send.
Anyway, I wanted to share a hymn from the St. Gregory Hymnal which was used in grade school when we went to daily Mass, a prayer to one's guardian angel. There are more stanzas, but these are what Nicola Montani, the St. Gregory Hymnal editor selected.
1. Dear angel ever at my side,
How loving must thou be,
To leave thy home in heaven to guide
A little child like me.
2. Thy beautiful and shining face,
I see not, though so near;
The sweetness of thy soft low voice,
I am too deaf to hear.
3. But when, dear Spirit, I kneel down,
Both morn and night to prayer,
Something there is within my heart,
Which tells me thou are there.
4. Oh, when I pray, thou prayest too
Thy prayer is all for me;
But when I sleep, thou sleepest not,
But watchest patiently.
5. Then for thy sake, dear Angel, now
More humble will I be:
But I am weak, and when I fall,
Oh, weary not of me:
6. Then love me, love me, angel dear!
And I will love thee more;
And help me when my soul is cast
Upon the eternal shore.
