Sacrament of Reconciliation
If a Christian’s conscience is burdened by serious sin, then the path of penance through the sacrament of Reconciliation becomes necessary for full participation in the Eucharistic Sacrifice.” “It is thanks to the medicine of confession that the experience of sin does not degenerate into despair.In the life of the body a man is sometimes sick, and unless he takes medicine, he will die. Even so in the spiritual life a man is sick on account of sin. For that reason he needs medicine so that he may be restored to health; and this grace is bestowed in the Sacrament of Penance. St Thomas Aquinas
