The Catholic Church teaches that the keeping of the sacraments are necessary for salvation. In their catechism, page 292, #1129 states:
The Church affirms that for believers the sacraments of the New Covenant are necessary for salvation.”
What does the Catholic Church consider a sacrament? In their catechism, page 289 #1113 states:
“There are seven sacraments in the Church: Baptism, Confirmation or Chrismation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony.”
"The sharing in the divine nature given to men through the grace of Christ bears a certain likeness to the origin, development, and nourishing of natural 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."3
