The faithful are more perfectly bound to the Church by the sacrament of Confirmation,
and the Holy Spirit endows them with special strength
so that they are more strictly obliged to spread and defend the faith,
both by word and by deed, as true witnesses of Christ.
Vatican II, Lumen Gentium
The sacraments of Christian initiation - Baptism, Confirmation, and the Eucharist - lay the foundations of every Christian life... "the faithful are born anew by Baptism, strengthened by the sacrament of Confirmation, and receive in the Eucharist the food of eternal life. By means of these sacraments of Christian initiation, they thus receive in increasing measure the treasures of the divine life and advance toward the perfection of charity.
