For centuries there was no particular ritual for marriage in the Church.
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.
It does mean, however, that the conscious choice by a married couple not to have a family for reasons of personal comfort and accommodation, the desire for luxury and freedom, the fear of responsibility, the refusal of sharing material possessions, the hatred of children, etc., is not Christian, and can in no way be considered as consonant with the biblical, moral and sacramental teachings and experience of the Orthodox Church about the meaning of life, love and marriage.
In light of the perspective offered above, the control of the conception of children in marriage is a very delicate matter, discouraged in principle and considered as perhaps possible only with the most careful examination of conscience, prayer and pastoral guidance.
The abortion of a child already conceived is strictly forbidden in the Orthodox Church, and cannot be justified in any way, except perhaps with the greatest moral risk and with the most serious penitence in the most extreme cases such as that of irreparable damage to the mother or her probable death in the act of childbirth.
