The two Christians expressed their mutual love in the Church and received the blessing of God upon their union which was sealed in the holy eucharist of Christ. They are crowned with the crowns of God’s glory to be his children and witnesses (martyrs) in this world, and heirs of the everlasting life of his Kingdom.
Through the Church’s formal recognition of the couple’s unity, and its incorporation into the Body of Christ, the marriage became Christian; that is, it became the created image of the divine love of God which is eternal, unique, indivisible and unending. They fulfill their marriage, as all sacraments are fulfilled, by their reception together of holy communion in the Church. It is, in essence, the “baptizing and confirming” of human love in God by Christ in the Holy Spirit.
A "yardstick for truth" is needed by which to compare what the Church originally believed and practiced with what these groups proclaim.
Certainly we all have the God-given right to believe whatever we desire and to participate in whatever religious association we choose.
Because of the realization of the need for Christ in every aspect of human life, and because, as well, it is the firm Christian conviction that nothing should, or even can, be done perfectly without Christ or without his presence and power in the Church by the Holy Spirit, two Christians cannot begin to live together and to share each other’s life in total unity—spiritually, physically, intellectually, socially, economically—without first placing that unity into the eternity of the Kingdom of God through the sacrament of marriage in the Church.
According to the Orthodox teaching as expressed in the sacramental rite of marriage, the creation of children, and the care and love for them within the context of the family, is the normal fulfillment of the love of a man and woman in Christ.
In Christian marriage the Holy Spirit is given so that what is begun on earth does not “part in death” but is fulfilled and continues most perfectly in the Kingdom of God.
According to Christ, in order for the love of a man and woman to be that which God has: perfectly created it to be, it must be unique, indestructible, unending and divine.Through penance, however, and with the sincere confession of sins and the genuine promise of a good life together, the Orthodox Church does have a service of second marriage for those who have not been able to fulfill the ideal conditions of marriage as taught by Christ.It is the practice of the Church as well not to exclude members of second marriages from the sacrament of holy communion if they desire sincerely to be in eucharistic fellowship with God, and if they fulfill all other conditions for participation in the life of the Church.The Orthodox Church carefully guards the truth against all error and schism, both to protect its flock and to glorify Christ, whose Body the Church is.An astonishing number of religious groups today claim to be the successors of the early Church.
