Sacramentos y Ceremonias
The sacraments of the New Law were instituted by Christ and are seven in number: Baptism, Confirmation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony. The seven sacraments correspond to all the stages and important moments of Christian life: they give birth and growth, healing, and mission to the life of faith of Christians. There is a certain similarity here between the stages of natural life and the stages of spiritual life.
