Mortal sin in the context of "Christian views on sin"

The sacrament of penance (also commonly called the reconciliation or confession) is one of the seven sacraments of the Catholic Church (known in Eastern Christianity as sacred mysteries). Through this sacrament, the faithful are absolved of sins committed after baptism and reconciled with the Christian community. During reconciliation, mortal sins must be confessed and venial sins may be confessed for devotional reasons. According to the dogma and unchanging practice of the church, only those ordained as priests may grant absolution.

The Mass is the central liturgical service of the Eucharist in the Catholic Church, in which bread and wine are consecrated and become the body and blood of Christ. As defined by the Church at the Council of Trent, in the Mass "the same Christ who offered himself once in a bloody manner on the altar of the cross, is present and offered in an unbloody manner". The Church describes the Mass as the "source and summit of the Christian life", and teaches that the Mass is a sacrifice, in which the sacramental bread and wine, through consecration by an ordained priest, become the sacrificial body, blood, soul, and divinity of Christ as the sacrifice on Calvary made truly present once again on the altar. The Catholic Church permits only baptised members in the state of grace (Catholics who are not in a state of mortal sin) to receive Christ in the Eucharist.

Many of the other sacraments of the Catholic Church, such as confirmation, holy orders, and holy matrimony, are generally administered within a celebration of Mass, but before the Second Vatican Council were often or even usually administered separately. The term Mass, also Holy Mass, is commonly used to describe the celebration of the Eucharist in the Latin Church, while the various Eastern Catholic liturgies use terms such as Divine Liturgy, Holy Qurbana, and Badarak, in accordance with each one's tradition.

According to Catholicism, a venial sin is a lesser sin that does not result in a complete separation from God and eternal damnation in Hell as an unrepented mortal sin would. A venial sin consists in acting as one should not, without the actual incompatibility with the state of grace that a mortal sin implies; they do not break one's friendship with God, but injure it.

In the Catholic Church, the anointing of the sick, also known as extreme unction, is a Catholic sacrament that is administered to a Catholic "who, having reached the age of reason, begins to be in danger due to sickness or old age", except in the case of those who "persevere obstinately in manifest grave sin". Proximate danger of death, the occasion for the administration of Viaticum, is not required, but only the onset of a medical condition of serious illness or injury or simply old age: "It is not a sacrament for those only who are at the point of death. Hence, as soon as anyone of the faithful begins to be in danger of death from sickness or old age, the fitting time for him to receive this sacrament has certainly already arrived."

Despite that position, anointing of the sick has in practice often been postponed until someone is near dying, in spite of the fact that in all celebrations of this sacrament, the liturgy prays for recovery of the health of the sick person if that would be conducive to their salvation. In the past, it became increasingly administered only to the dying and so came to be called extreme unction (final anointing).

Catholic hamartiology is a branch of Catholic thought that studies sin. According to the Catholic Church, sin is an "utterance, deed, or desire", caused by concupiscence, that offends God, reason, truth, and conscience. The church believes sin is the greatest evil and has the worst consequences for the sinner (original sin and damnation), the world (human misery and environmental destruction), and the Catholic Church itself (Passion of Jesus and wounds to the church's unity). Based on the Bible, the Catholic Church distinguishes between two kinds of sins: mortal sin and venial sin. The Catholic Church also distinguishes between the state of being in original sin and the commission of actual sin.
