The document discusses the Catholic understanding of sacraments. It defines sacraments as outward signs instituted by Christ that give grace by signifying and causing inward spiritual effects. It explains that sacraments are efficacious symbols that do more than just point to grace, but actually bring it about. There are seven sacraments in the Catholic tradition divided into categories of initiation, healing, and mission/service. The sacraments are seen as channels of God's grace that communicate divine life to those who receive them.
