Good News Book Store & Religious Goods has a large supply of Catholic Sacramental Jewelry. Scarmentals such as medals and crucifixes worn by Catholics as Sacred signs by which spiritual effects are signified and are obtained by the intercession of the Church. In this context a catholic wearing a crucifix or a medal the sacramental refers primarily to a sign, an object or prayer that provides the occasion for a personal and "gracing encounter" with Christ.
The spiritual effect following from the use of a sacramental such as "saint medal" or a crucifix worn around the neck depends upon the intercession of the Catholic Church. Underlying this assertion is, ultimately, the notion that the church, as the body of Christ is so united with him that her actions and formally approved prayers have their own peculiar efficacy.
