where is the host kept in the church
Church tabernacle When Orthodox Christians receive Holy Communion, they always receive in both species: the Body and the Blood of Christ. This includes Communion taken to the sick. Therefore, both are reserved in the tabernacle. Every year on Holy Thursday, the reserved Mysteries are renewed. The priest will cut an extra Lamb (host) for that liturgy and after the consecration, just before the clergy receive communion, the priest will take the extra Lamb and carefully pour a little of the Blood of Christ over it. This Lamb will then be cut into very small portions, allowed to dry thoroughly, and be placed in the tabernacle. The deacon (or priest, if there is no deacon) will consume whatever remains of the previous year's reserved sacrament when he performs the ablutions.
