Eastern Orthodox Church
Common part of the rite
The priest anoints the recipient with chrism, making the
sign of the cross on the forehead, eyes, nostrils, mouth, ears, breast, hands, and feet using the following words each time: "The seal of the gift of the
Holy Spirit" (in
Greek: Σφραγὶς δωρεᾶς Πνεύματος Ἁγίου).
The chrism is washed off by a priest seven days later, according to the written
rubrics, the newly baptized wearing their white
chitons and not washing their anointed parts for that period. However, in the case of infant baptism (and often also with adult chrismation contemporary practice), the ablution is performed immediately after the rite of chrismation.
As part of the baptismal rite
Typically, one becomes a member of the Church by baptism and chrismation performed by a priest as a single service, or subsequent to baptism performed by a layman. While chrismation is often performed without baptism, baptism is never performed without chrismation; hence the term "baptism" is construed as referring to the administration of both sacraments (or mysteries), one after the other.
At the reconciliation of apostates
Eastern Orthodox Church the sacrament may be conferred more than once as it is customary to receive apostates by repeating chrismation;
 according to the Book of Needs, the priest "taking the Holy Chrism, he anoints him (her) according to the order of those who are baptized ..." towards the end of the "Prayers of Purification for One Returning to the True Faith from Apostasy".
This practice is thus attested to in the ninth century by
Saint Methodius of Constantinople in "The Rule of Methodius, Patriarch of Constantinople, Concerning the Return from Apostasy of Various Persons to the True Orthodox Faith":
If a child ... is in apostasy ... let him be washed. Upon leaving the bath, girded with a linen cloth, let him be anointed with Chrism, as one who is baptized. And let him put on a new robe in the manner of those who have been baptized.
If ... one who is of age has renounced his impending torment ... then let him be washed and anointed with Chrism according to the accepted Rite. And when the Liturgy is celebrated, let him be counted worthy of the Holy Things, occupying himself in Church and the Liturgy, as them that are baptized ...
At the reception of certain converts
Although normally administered in conjunction with baptism, in some cases chrismation alone may be used to receive
converts to Orthodoxy through the exercise of
economia. Although practice in this regard varies, in general, if a convert comes to Orthodoxy from another Christian confession and has previously undergone a rite of baptism in the Trinitarian Formula ("in the Name of the Father, and of the Son, and of the Holy Spirit"), he or she may be received into the Orthodox Church through the sacrament of chrismation, after which receiving the Holy Eucharist. If, however, a convert comes from a Christian confession that baptizes in the name of Jesus (such as
Oneness Pentecostals), from one which practices an invalid, non-Trinitarian baptism (such as
Jehovah's Witnesses) or from one that does not practice baptism at all (such as
The Salvation Army), baptism is a prerequisite for chrismation—an initiate must always be validly baptized into the death of Jesus in the name of the Holy Trinity before any further holy mysteries or sacraments of initiation can be administered. The use of economia is at the discretion of, and subject to the guidelines imposed by, the local
bishop. Converts from non-Christian religions also need to be baptized before chrismation.
The sacrament of chrismation is an extension of the day of
Pentecost, on which the Holy Spirit was poured out on the Apostles. It is by chrismation that a person becomes a layperson — a member of the laos (laity), the people of God.
Kallistos (Timothy Ware) explains:
Through Chrismation every member of the Church becomes a prophet, and receives a share in the royal priesthood of Christ; all Christians alike, because they are chrismated, are called to act as conscious witnesses to the Truth. "You have an anointing (chrisma) from the Holy One, and know all things" (1John 2:20).
Oriental Orthodox churches
Chrismation in Oriental Orthodoxy is similar to that of Eastern Catholicism or Orthodoxy but is done according to their sacramental theology, and may vary according to the particular church.
