 The concept of Mary offering Christ's sufferings is theologically complex.Christ offered himself alone; “the Passion of Christ did not need any assistance.” It is according to the spirit of the offertory or preparation of the gifts within the Mass to prepare to offer oneself with Christ as a part of the Eucharistic Prayer, being members of his mystical body, acknowledging that not even the greatest effort, of itself and apart from Christ, can be of any significance to God.A priest participates in the Eucharistic Celebration as an icon of Christ.
