The veneration of relics continues to be of importance in the Eastern Orthodox Church. As a natural outgrowth of the concept in Orthodox theology of theosis, the physical bodies of the saints are considered to be transformed by divine grace—indeed, all Orthodox Christians are considered to be sanctified by living the mystical life of the Church, and especially by receiving the Sacred Mysteries (Sacraments). In the Orthodox service books, the remains of the departed faithful are referred to as "relics", and are treated with honour and respect. For this reason, the bodies of Orthodox Christians are not traditionally embalmed.
