Latin anyone?

[Crucifer]

Could I have a bit of translation done please? The following text into Latin, as accurately as possible.

The Russian Contakion for the Departed:

Give rest, O Christ, to thy servant with thy saints; where sorrow and pain are no more; neither sighing, but life everlasting. Thou only art immortal, the creator and maker of men; and we are mortal, formed of the earth, and unto earth shall we return; for so thou didst ordain, when thou createdst man, saying: "Dust thou art, and unto dust shalt thou return." All we go down to the dust, and weeping o'er the grave we make our song. Alleluya.

Crossposted with B77, FOEM and inkify.

Thanks.
