I have met priests that take this matter very seriously, those that are completely hands-off on the topic, and those that don't consider birth control a big deal at all. As a parent of many children, I am decidedly in the pro-progeny camp. We seem to have taken individual instances where economia is called for (medical problems, extreme family issues, etc.) and recast being closed to life as a normal "choice." This is not only lamentable in its immediate effect on the family, but also on the every shrinking Orthodox birthrate. We are blithely not procreating ourselves into non-existence in a way that jihadi Islam, Communism, and radical enviro-secularism could only dream about.
(The Morning Offering) - Marriage, for the Orthodox Christian, is to have as it's foundation, Jesus Christ, and a commitment to live in full communion with the Church. When a couple are joined together in this mystical (sacramental) union with one another, they become one flesh, and begin their relationship as one. The crowning ceremony symbolizes martyrdom of self and a commitment to sacrifice self-will.
Marriage is not about sexual gratification, although sexual intimacy is an important component of any healthy marriage, but the intimacy of the marriage bed be open to the possibility of having children. The Church allows no form of contraception that is abortifacient, and the Fathers of the Church, such as Ss. Athanasius the Great, John Chrysostom, Epiphanios, Jerome, Ambrose, Augustine of Hippo, Caesarious, Gregory the Great, Augustine of Canterbury and Maximos the Confessor, all explicitely condemned abortion as well as the use of abortifacients.
There are a range of opinions on the issue of non-abortifacient contraception, however, the bottom line is that a Christian couple must be open to having children. A couple who would choose to have no children, or limit the number of children based on a desire for financial and lifestyle security, forgo the joy that only children can bring to a Christian marriage. Birth control should never be based on selfish motives, or the desire to live a more comfortable lifestyle. This life is not meant for personal gratification, nor personal gain, but that we might give glory and worship to God in all we do.
With love in Christ,
