Baptism incorporates the person who receives it into the Life, Death and Resurrection of Christ and into his saving action. This sacrament leaves in the Christian an indelible spiritual seal of belonging to Christ. Through Confirmation, Christians participate more fully in Christ’s mission and in the fullness of the Holy Spirit. A baptised and confirmed Christian is destined to take part in the Church’s mission of evangelising by virtue of these two sacraments.

The Eucharist makes Jesus Christ present. He invites us to accept the salvation that He offers us, and to receive the gift of His Body and Blood as the food of eternal life. Our Lord announced the Eucharist during his public life and instituted this sacrament at the Last Supper. When the Church celebrates this sacrament, she follows the Eucharistic rite carried out by Christ at the Last Supper.

The Holy Mass makes present, in the Church’s daily liturgical life, the one sacrifice of our redemption. The Mass is a true and proper sacrifice because it makes sacramentally present the one, perfect and definitive sacrifice of the Cross.

The desire to receive Holy Communion should always be present in Christians: what food produces in the body for the good of physical life, the Eucharist produces in the soul.

Penance is a sacrament which brings healing and salvation from sin. Over the course of history, the ministers of Christ and the Church have exercised the power to forgive sins in different ways.

Eternal law, natural law, the New Law or Law of Christ, human political and ecclesiastical laws are all moral laws in a very different sense, although they all have something in common.

Only voluntary actions are the object of a moral evaluation properly speaking. The education of the complex world of feelings is a fundamental part of Christian formation and life. The path for ordering the passions is the acquisition of moral habits called virtues. The object, the intention and the circumstances are the “sources” or constitutive elements of the morality of human acts.

Marriage is an institution foreseen by God in his wisdom, so as to carry out in humanity his divine plan of love. It is born of the personal and irrevocable consent of the spouses. The essential properties of marriage are unity and indissolubility.
