Prayer when we learn of someone’s death

Rest, O Christ, the soul of your departed servant, where there is no disease, no weeping, no sorrow, no grief, but only endless, joyful, happy and blessed life with you in your heavenly Kingdom. For you are the resurrection, life, and eternal rest, O our God Christ, and we glorify you with the Eternal Father and the Holy Spirit, now and ever, and unto ages of ages. Amen.
