As a devotional part of the eucharistic liturgy, the Agnus Dei also carries a missional aspect. Exegeting the verse Jn 1.29 (‘Behold the Lamb of God…’) two major theories of the atonement are seen to be involved and are applicable to the meaning of the Agnus Dei. These two theories of the atonement (ransom and substitutionary) in their relationship to each other are noted, and a primary emphasis on the ransom theory and its background of the Passover is argued for. The Passover Lamb focus is seen as liberative and missional. This leads to seeing the Agnus Dei in its referring to the redeeming death of Christ (‘Lamb of God’) as appropriately accompanied by the fraction of the bread. The history of the Agnus Dei and its Eastern Orthodox roots are brought to bear, as are our modern Anglican liturgical forms.

The object described and discussed in this paper is a recently found Anglo-Saxon strap-end. Although incomplete, the strap-end is of interest in view of its rarity in being made of silver, of its decoration and of it containing an inscribed text. One part of the decoration is a depiction of the agnus dei. In the discussion, the decoration on the strap-end, and its significance, is set in the context of other instances of the agnus dei, both on artefacts and in manuscripts, from late Anglo-Saxon England.
