A sacrament is an outward sign instituted by Christ to give grace. (Baltimore Catechism #574)
Man is made of soul and body, and through this reality, Jesus instituted 7 Sacraments to share his Divine life with us. The Church has identified 7 Sacraments, using Scripture and Tradition, to enable men and women throughout history to encounter the Blessed Trinity and receive grace in order to live their lives in union with God.
The seven sacraments touch all the stages and all the important moments of Christian life:1 they give birth and increase, healing and mission to the Christian’s life of faith. There is thus a certain resemblance between the stages of natural life and the stages of the spiritual life. (CCC 1210)
The 7 Sacraments are Baptism, Confirmation, Holy Eucharist, Reconciliation, Holy Orders, Matrimony, and Anointing of the Sick. When a Catholic receives these Sacraments, God sends his grace upon the individual(s) in order to share in His life and gain strength to live as a true faithful disciple of our Lord.
