Sacraments are use of matter (objects to reveal otherwise unperceivable spiritual realities. The following video might help with definition of sacraments.
“The Seven Sacraments touch all stages and all the important moments of Christian life.” (CCC 1210) There is a resemblance between the stages of natural life and spiritual life. (Ibid) Code of Canon Law states, “The sacraments of the New Testament were instituted by Christ and entrusted to the Church. As actions of Christ and the Church, they are signs and means which express and strengthen the faith, render worship to God, and effect the sanctification of humanity and thus contribute in the greatest way to establish, strengthen, and manifest ecclesiastical communion.”(CIC. 840) Therefore, the sacraments are for the sanctification of the faithful to reach the heavenly reality God promised.
“The sacramental mystery lies at the heart of the Christian life in the Church. Because it is through the Church and in the sacraments, that God the Father through His Son by the working of the Holy Spirit communicates His divine life to His people.” (Paul Haffner, The Sacramental Mystery, Herfordshire, England, 2008, p.1.)
There are seven sacraments which are: Baptism, Confirmation, Eucharist, Reconciliation, Anointing of the Sick, Holy Orders, and Marriage. They are split into 3 categories by the Catechism of the Catholic Church: Initiation, Healing, and Service of Communion (Vocation). Every sacrament, however, has a healing effect on the soul and in certain cases physical and psychological healing.
“In general, the grace imparted by the sacraments renders God’s love, presence and power available in the present moment, in a way which is specific to each sacrament.” (The Sacramental Mystery, p. 21.) “The heavenly dimensions of the Sacraments manifests our participation in His New Creation.” (Ibid. p. 22) The sacraments therefore, are for each of us to be used to guide the lives of each faithful to a more complete and fulfilling life through Christ and his Church to reach God in heaven.
