Church tabernacle  A tabernacle is a fixed, locked box in which, in some Christian churches, the Eucharist is "reserved" (stored). A less obvious container for the same purpose, set into a wall, is called an aumbry. Within Catholicism, Eastern Orthodoxy and in some congregations of Anglicanism and Lutheranism, a tabernacle is a box-like vessel for the exclusive reservation of the consecrated Eucharist. It is normally made of metal, stone or wood, is lockable and secured to its altar or adjacent wall to prevent the consecrated elements within from being removed without authorization. The "reserved Eucharist" is secured there for distribution at services, for availability to bring Holy Communion to the sick, and, especially in the Western Church, as the centre of attention for meditation and prayer. The term "tabernacle" arose for this item as a reference to the Old Testament tabernacle which was the locus of God's presence among the Jewish people – hence, it was formerly required (and is still generally customary) that the tabernacle be covered with a tent-like veil (conopaeum) or curtains across its door when the Eucharist is present within. By way of metaphor, Catholics and Orthodox alike also refer to the Blessed Virgin Mary as the Tabernacle in their devotions (such as the Akathist Hymn or Catholic Litanies to Mary), as she carried within her the body of Christ in her role as Theotokos. The following historical information is found, for instance, in the article "The casing of the Eucharist" by the Secretary of the Congregation for the Clergy, Archbishop Mauro Piacenza, who also heads the Pontifical Commission for the Cultural Patrimony of the Catholic Church, in "30Days", No. 6 Year XXIII – June 2005. In early Christianity, priests and or lay people commissioned by them took bread consecrated at their Eucharist to their homes, in order to give it to the sick and others unable to attend the celebration. But when the Edict of Milan ended persecution, and the early Church was allowed to practice its religion publicly, the Eucharist was no longer kept safeguarded in private Christian homes, but was reserved near the altars of churches  The preferred containers, the original "tabernacles", then had the form of a (usually gold) dove within a (usually silver) tower.
