Icon corner

The icon corner, or red corner, (Greek: εικονοστάσι and Russian: Кра́сный у́гол - Krásnyj úgol - meaning red, bright-shining, or beautiful corner) is a small worship space prepared in the homes of Eastern Orthodox and Greek-Catholic Christians. The analogous concept in Western Christianity is the home altar.

The Book of Acts and the Epistles of the Apostle Paul record that in the early Church, Christians used to meet in the homes of the faithful. (Acts 2:46, Acts 20:7-12, 1 Corinthians 16:19, etc.) This tradition of the "House Church" continues to this day in Eastern Christianity. The home is considered to be a microcosm of the Church. The parents (both the husband and the wife) are the "clergy" of the house church, and the children are the "laity." The wedding ceremony ("crowning") is analogous to Ordination, and the house is blessed with a rite that is based upon the Consecration of a Church. Once a year, the priest will come to bless the house with Theophany Water.

An Orthodox Christian is expected to pray constantly. According to Bishop Kallistos Ware, "[I]n Orthodox spirituality, [there is] no separation between liturgy and private devotion." Thus the house, just like the Temple (church building), is considered to be a consecrated place, and the center of worship in the house is the icon corner.
