This catechism presents the beliefs and practices it considers necessary for serving God and attaining salvation. It begins with established prayers, the Apostles’ Creed, and acts of faith, hope, love, and contrition, explaining prayer as worship, trust, repentance, spiritual defense, and reliance on divine providence. It then teaches humanity’s purpose, the soul, reason, free will, revelation, creation, the Trinity, angels, the Fall, sin, virtue, grace, and redemption through Jesus Christ. It develops Christ’s Incarnation, life, Passion, death, Resurrection, and Ascension, followed by the mission of the Holy Ghost. The Church is described as a visible, authoritative, infallible, indefectible, one, holy, catholic, and apostolic means of salvation under the Pope and bishops. The catechism explains the seven sacraments, their signs, ministers, effects, dispositions, and permanent character, with particular attention to Baptism, Confirmation, and Penance. It teaches truthful confession, contrition, penance, restitution, and indulgences; presents the Eucharist as Christ truly present and the Mass as the same sacrifice as Calvary; and discusses Communion, Extreme Unction, ordained ministry, and Matrimony. Later sections cover sacramentals, images, relics, the Rosary, holy water, the Ten Commandments, Church precepts, judgment, heaven, purgatory, hell, and resurrection. Throughout, it emphasizes repentance, moral responsibility, faithful practice, and perseverance.
