Hostiethumb|Hosties dans le rite catholique. L'hostie, dans les rites liturgiques chrétiens, est du pain sans levain que l'officiant consacre pendant la célébration de l'Eucharistie pour le partager avec les fidèles au cours de la communion.

Anglican CommunionThe Anglican Communion is the third largest Christian communion after the Roman Catholic and Eastern Orthodox churches. Founded in 1867 in London, the communion has more than 85 million members within the Church of England and other autocephalous national and regional churches in full communion. The traditional origins of Anglican doctrine are summarised in the Thirty-nine Articles (1571). The archbishop of Canterbury (, Justin Welby) in England acts as a focus of unity, recognised as primus inter pares ("first among equals"), but does not exercise authority in Anglican provinces outside of the Church of England.

Le mot « homélie » vient du latin homilia, dérivé du ὁμιλία, homilía.

Closed communionClosed communion is the practice of restricting the serving of the elements of Holy Communion (also called Eucharist, The Lord's Supper) to those who are members in good standing of a particular church, denomination, sect, or congregation. Though the meaning of the term varies slightly in different Christian theological traditions, it generally means that a church or denomination limits participation (with respect to the Eucharist) either to members of their own church, members of their own denomination, or members of some specific class (e.
