Chrismation consists of the sacrament or mystery in the initiation rites of Eastern Christianity as practiced in the Eastern Orthodox Church, Oriental Orthodox Churches, Assyrian Church of the East and Eastern Catholic churches. The sacrament is more commonly known in Western Christianity as confirmation, although some languages such as Italian, Maltese and Portuguese normally use the terms cresima, griżma (tal-isqof) and crisma ("chrismation") rather than confermazione, konferma or confirmação, respectively ("confirmation").
The term chrismation comes about because it involves anointing the recipient of the sacrament with chrism (holy oil), which according to eastern Christian belief, the Apostles sanctified and introduced for all priests to use as a replacement for the laying on of hands by the Apostles.
