Due to the existence of counterfeit relics, the Church began to regulate the use of relics. Canon Law required the authentication of relics if they were to be publicly venerated. They had to be sealed in a reliquary and accompanied by a certificate of authentication, signed and sealed by someone in the Congregation for Saints, or by the local Bishop where the saint lived. Without such authentication, relics are not to be used for public veneration. The Congregation for Saints, as part of the Roman Curia, holds the authority to verify relics in which documentation is lost or missing. The documents and reliquaries of authenticated relics are usually affixed with a wax seal.
