The Liturgy of Public Penance
The Liturgy of public penance had three components. First, penitents presented themselves to their bishop and confessed their sins to him. Their separation from the Body of Christ, excommunication, “was based on the viewpoint that the Church, taken in its fullest sense, is or should be a community of saints; whoever, by sin, has lost the life of grace no longer belongs to the Church in this full sense” (Josef A. Jungmann, S.J., The Early Liturgy, 242-43). However, penitents were not completely rejected because the Church ardently desired to bring about their forgiveness and reconciliation. In this solemn ritual, the individuals wore a penitential garb and had their heads strewn with ashes by the bishop. In the Orient, they were allowed to be present at the Liturgy of the Word, after which they were dismissed. In the West, penitents were permitted to be present at the Liturgy but stood at the back of the church during the liturgy. In either case, they could not receive Holy Communion. This painful deprivation was a stark reminder that they had severed themselves from the Church. The New Commentary of Canon Law (1998) addresses the issue of excommunication in our time (See for example, # 1319, 1131, 1364, 1367, 1372, 1378, 1398). Canon 915 of The New Commentary of Canon Law details the current prohibition of the Eucharist to public sinners.
Second, at every episcopal service, a penitent received from the bishop a special blessing. Finally and at the end of a period of time, the decisive act concluded the term of penance. In the liturgy of reconciliation, the excommunication, accompanied by prayer and imposition of hands, was withdrawn. The bishop gave each penitent absolution from his or her sin. This act of reconciliation was a sacramental act proper. The penitent was again received into the Church and again introduced as a member of the Body of Christ. The bishop declared that the penitent once more was to be a full member of the Church. This was a time of rejoicing for the entire community.
