"The Vesperal Divine Liturgy of St Basil commemorating the Last Supper of the Lord and the Institution of the Holy Eucharist therefrom.
In this Liturgy there is consecrated an extra portion of the Eucharistic loaf (called "the Lamb") which is then dried and kept in the artoforion (tabernacle) on the Holy Table until the next year's Great and Holy Week. This is used (exclusively) for communing sick persons who cannot come to church. The remains of last year's consecrated Lamb are placed in the chalice and consumed.
The Lord's explicit command (DO THIS!) in instituting the Eucharist places this right at the heart of Christian worship, faith and life. By this means we are fed spiritually, granted all the heavenly blessings of the Kingdom and receive a foretaste of our longed for theosis when we shall be fully one, (and with each other), in our Lord and God and Saviour Jesus Christ. In this sacred meal He comes and feeds us with Himself in Holy Communion. What a wonderful gift!" By: Fr. Gregory Hallam
