The Sacrament is kept in a Ciborium. For adoration, the Holy Eucharist is displayed in a monstrance.
The place where the host is kept in church is called the Tabernacle. It is a locked box or cabinet where consecrated hosts (the Eucharist) are stored for adoration, communion, and to be taken to the sick.
He consecrated the host for communion.
It is called a host
A monstrace is a vessel used to display a consecrated host. Typically, it is a starburst design with the host in the center clear window.
The paten is the saucerlike disk that it used to hold the Host when it is being consecrated.
Roman Catholic AnswerStrictly speaking, they should only be called "Hosts" when they are consecrated and are now physically and really the Body of Christ, at which point they would be on the altar, or stored in the Tabernacle. The small rounds wafers used for Hosts are just bread and usually stored in the sacristy or a convenient freezer before use, they are not technically "hosts" before they are used, just wafers.
Consecrated Hosts are stored in a locked Tabernacle, not on the altar. The Tabernacle may be located immediately behind the main altar or on its own pedestal in the Church, non on the altar.
I am tempted to say the priest, but you are asking about a thing. The thing that the Host rests on when it is consecrated is a paten. The thing that the Host rests in when it is in the tabernacle is a ciborium. The thing that the Host is displayed in is an ostensorium or monstrance. You didn't specify which "thing".
Yes it is. Preferably, after it has been consecrated, it would be better to use the term Body of Christ.
A monstrance is a receptacle used for holding a Consecrated Host (as Catholics be believe that when the bread [hosts] and wine are Consecrated during Mass they truly become the Body, Blood, Soul, and Divinity of Jesus Christ) for Adoration by the faithful.
In Catholic churches the tabernacle contains the excess hosts consecrated at earlier Masses. Also, a 'luna' (large consecrated host) is held there so that Christ is always present, even if there are no excess hosts. The 'luna' is the host that is used for adoration and benediction.
