In the first part of foregoing article there are presented origins of the relics cult and its evolution in history of Church. The second part of publication gets together causes and reasons that justify this type of cult and places it in the context of broader Christian cult. The cult of saints and of their relics as a consequence plays the secondary role in reference to the devotion to God Himself as well as to the Christ’s Revelation and his paschal mystery. Its legal validity is confirmed by the statements of Church’s authority as well as theological rationales and ascetic activities. But it requires the permanent pastoral supervision to be saved against aberrations which appeared in the history of Church.
