Consecrations in Eastern Christianity can refer to either the Sacred Mystery (Sacrament) of Cheirotonea (Ordination through laying on of hands) of a bishop, or the sanctification and solemn dedication of a church building.
It can also (more rarely) be used to describe the change of the bread and wine into the Body and Blood of Christ at the Divine Liturgy.
Just as in Acts there were two stages involved: (a) election and (b) the prayerful laying on of hands, so the Ordination of a bishop in the Eastern Church takes place in two stages:[note 1] The Greek words meaning ‘dedicate’ and ‘dedication’ are not easy to translate into English, since they also have the connotation of ‘newness’, ‘renewal’.
Many biblical elements taken from the Consecration of the Tabernacle (Exodus 40) and the Temple of Solomon (1 Kings 8; 2 Chronicles 5–7) are employed in the service.
Before construction begins on a new church, the bishop or his representative lays a foundation stone which may or may not contain relics of a saint.
If the term "Consecration" is used to refer to the change of the Eucharistic elements (bread and wine) into the actual Body and Blood of Christ, the Eastern Christians emphasize that the Consecration is the Divine response to the Epiclesis, in which the priest invokes the Holy Spirit to come down upon the Gifts and change them.
Unlike the prevailing opinion in the West, the Eastern Christians do not hold that there is one specific moment at which this "change" takes place; it is a Sacred Mystery, which begins with the Prothesis (see Liturgy of Preparation).
Persons from other Christian confessions who are not received into the Church by Baptism may be admitted by Chrismation (depending upon the regulations of the jurisdiction).
[note 5] Apostates who have left the Church and then repented and returned are restored after appropriate penance to full communion through Chrismation.
In the early church, after an individual was Baptized, one of the Apostles would then lay hands upon them and they would receive the Holy Spirit (Acts 8:14–17).
The Antimins (literally, "In place of the Table") is a piece of cloth, often silk, that has depicted on it Christ laid out for burial with Icons of the four Evangelists in the corners.
