The Tallis Scholars & Peter Phillips funeral ikos

Why these bitter words of the dying,
O brethren,
which they utter as they go hence?
I am parted from my brethren.
All my friends do I abandon and go hence.
But whither I go, that understand I not,
neither what shall become of me yonder;
only God who hath summoned me knoweth.
But make commemoration of me with the song:
Alleluia. Alleluia. Alleluia. Alleluia.
But whither now go the souls?
How dwell they now together there?
This mystery have I desired to learn,
but none can impart aright.
Do they call to mind their own people
as we do them?
Or have they forgotten all those
who mourn them and make the song:
Alleluia. Alleluia. Alleluia. Alleluia.
We go forth on the path eternal,
and as condemned, with downcast faces,
present ourselves before the only God eternal.
Where then is comeliness?
Where then is wealth?
Where then is the glory of this world?
There shall none of these things aid us,
but only to say oft the psalm:
Alleluia. Alleluia. Alleluia. Alleluia.
If thou hast shown mercy unto man,
O man, that same mercy
shall be shown thee there;
and if on an orphan
thou hast shown compassion,
the same shall there deliver thee from want.
If in this life the naked thou hast clothed,
the same shall give thee shelter there,
and sing the psalm:
Alleluia. Alleluia. Alleluia. Alleluia.
Youth and the beauty of the body fade
at the hour of death, and the tongue
then burneth fiercely,
and the parched throat is inflamed.
The beauty of the eyes is quenched then,
the comeliness of the face all altered,
the shapeliness of the neck destroyed;
and the other parts have become numb
nor often say:
Alleluia. Alleluia. Alleluia.
With ecstasy are we inflamed if we
but hear that there is light eternal yonder;
that there is paradise, wherein every soul
of righteous ones rejoiceth.
Let us all, also, enter into Christ,
that all we may cry aloud thus unto God:
Alleluia. Alleluia. Alleluia.
