The sacrament of reconciliation through which the faithful confess their sins to a priest and receive absolution. Also called the sacrament of repentance or penance, confession restores the baptismal purity lost through sin and reconciles the penitent with God and the Church. The penitent stands before an icon of Christ while confessing to the priest, who acts as a witness and minister of God's forgiveness. The priest then covers the penitent's head with his epitrachelion (stole) and pronounces the prayer of absolution.
