The holy oil, chrism, or µvpov, as the Easterns call it, was prepared and consecrated on Maundy Thursday, and in the Gelasian sacramentary the formula used runs thus: "Send forth, 0 Lord, we beseech thee, thy Holy Spirit the Paraclete from heaven into this fatness of oil, which thou hast deigned to bring forth out of the green wood for the refreshing of mind and body; and through thy holy benediction may it be for all who anoint with it, taste it, touch it, a safeguard of mind and body, of soul and spirit, for the expulsion of all pains, of every infirmity, of every sickness of mind and body.
The Roman Church, without the sanction of an oecumenical council and without consulting the Easterns, added " and the Son."
The Easterns also resented the Roman enforcement of clerical celibacy, the limitation of the right of confirmation to the bishop and the use of unleavened bread in the Eucharist.
The Easterns allege that the addition of the words Filioque was made, not only without authority, and therefore unwarrantably, but also for the purpose of forcing a rupture between East and West in the interests of the barbarian empire of the West.
These proposals were rejected by the Easterns, who regarded them as attempts to enforce new creeds on their church.
Some of the Reformers, notably Melanchthon, expected to effect a reunion of Christendom by means of the Easterns, cherishing the same hopes as the modern Old Catholic divines and their English sympathizers.
