:It should be noted here at this point that the Orthodox exorcisms are in essence prayers for averting the influence of evil spirits rather than for expelling the devil, especially in ceremonies such as sanctifying the waters (Hagiasmos), blessing the ceremonial oil, or blessing sacred vessels. It should also be noted that the importance of exorcism in Orthodox ecclesiastical life is not as great as it is in both the Roman Catholic and Protestant Churches. In recent years certain semi-pagan exorcistic rituals have been practiced by a number of people uncertain as to their religious belonging, including clergymen of the Roman Catholic and Protestant Churches. Assuming the role of an exorcist is a serious offense against the Church's conception of evil and of the sacramental means by which it should be warded off. Needless to say, evil in man, whether personified or not, naturally requires the help of the Church for its expulsion but, above all, requires the spiritual strength of the individual concerned.<ref>Rev.

Prayer of interdiction of St. Basil the Great that is read by a priest over one suffering from demons
::O God of gods and Lord of lords, Creator of the fiery ranks, and Fashioner of the fleshless powers, the Artisan of heavenly things and those under the heavens, Whom no man has seen, nor is able to see, Whom all creation fears: Into the dark depths of Hell You hurled the commander who had become proud, and who, because of his disobedient service, was cast down from the height to earth, as well as the angels that fell away with him, all having become evil demons. Grant that this my exorcism being performed in Your awesome name, be terrible to the Master of evil and to all his minions who had fallen with him from the height of brightness. Drive him into banishment, commanding him to depart hence, so that no harm might be worked against Your sealed Image. And, as You have commanded, let those who are sealed receive the strength to tread upon serpents and scorpions, and upon all power of the Enemy. For manifested, hymned, and glorified with fear, by everything that has breath is Your most holy Name: of the Father, and of the Son, and of the Holy Spirit, now and ever and into ages of ages. Amen.
