Persons of the Reformed persuasion should note the following from the Eastern Orthodox service book is required to join the Eastern Orthodox church:
Dost thou renounce the false doctrine that, for the expression of the dogma touching the Procession of the Holy Spirit, the declaration of our Saviour Christ himself: “who proceedeth from the Father”: doth not suffice; and that the addition, of man’s invention: “and from the Son”: is required?
Dost thou renounce the false doctrine, that the predestination of men to their salvation, or their rejection, is not in accordance with the Divine foreknowledge of the faith and good works of the former, or of the unbelief and evils deeds of the latter; but in accordance with some arbitrary destiny, by reason of which faith and virtue are robbed of their merit, and God is held accountable for the perdition of sinners?
Dost thou renounce the erroneous belief that in the Sacrament of the Holy Eucharist the bread and wine are not transmuted into the Body and Blood of Christ, and are merely emblems of the Body and Blood of Christ?
Dost thou renounce the erroneous belief of the Reformed teachers, who reject five Sacraments: Chrismation, Confession, Marriage, Anointing with Oil, and the Priesthood itself, which administereth the other Sacraments, and presume to administer Baptism and the Eucharist, never having received, through the laying-on of hands by a Bishop, that Ordination which hath been transmitted from one to another, even from the holy Apostles?
Dost thou renounce the erroneous belief of the Reformed teachers who receive not the traditions of the Holy Church, reverence not the Saints, and deprive the dead of spiritual aid, and the living of consolation, in that they reject prayers for the dead?
