The Sacred Host

Regarding the use of the sacred Host which is utilised as the focus of prayer, adoration, and meditation in Eucharistic devotion - It remains in the tabernacle or aumbry with the rest of the Blessed Sacrament reserved for the Holy Communion of the sick. Once a week or thereabout, It is reverently consumed at Mass by the celebrant and replaced by another consecrated priest's Host. The Host is always therefore available to be consumed by the sick or by other persons who are unable to attend Mass but desire to receive the Holy Communion apart from a Eucharistic celebration. It is never left unconsumed and It is never neglected - It is always ultimately used in Communion. A very good question.
