The Sacraments are an outward sign instituted by Christ that impart divine grace to those receive the the sacraments. The seven Sacraments were instituted by Jesus and His Apostles and form an integral part of what it means to be a Christian. All celebrations of the Sacraments are done through the liturgical life of the Church.
The following is an excerpt from the Catechism of the Catholic Church.
THE SEVEN SACRAMENTS OF THE CHURCH
[1210] Christ instituted the sacraments of the new law. There are seven: Baptism, Confirmation (or Chrismation), the Eucharist, Penance, the Anointing of the Sick, Holy Orders and Matrimony. 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.
