It’s a complex issue, but:
Concerning contraceptives and other forms of birth control, differing opinions exist within the Eastern Orthodox Churches. In the past birth control was in general strongly condemned, but today a less strict view is coming to prevail, not only in the west but in traditional Eastern Orthodox countries. Many Eastern Orthodox theologians and spiritual fathers consider that the responsible use of contraception within marriage is not in itself sinful. In their view, the question of how many children a couple should have, and at what intervals, is best decided by the partners themselves, according to the guidance of their own consciences.”1
There are also Orthodox who say it should never be used at all.
Personally, I am at peace with the current Catholic discipline of never using contraception.
But all I’m saying is I would still be at peace if certain forms of contraception were allowed in some circumstances.
