"The whole liturgical life of the church revolves around the Eucharistic sacrifice and the sacraments. There are seven sacraments in the Church: Baptism, Confirmamation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony." Catechism of the Catholic Church 1113
The seven sacraments touch all the stages and all the important moments of Christian life: 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.
