On the web page for the Ukrainian Orthodox Church of Canada under beliefs and practices concerning birth control it states:
"The view of most Orthodox bodies is that controlling conception through “natural family planning”, or contraception, is acceptable for married couples, as long as it is done in a spirit of responsible Christian stewardship of life.
This means, first, that birth control will not be used merely because having and rearing children is seen as a financial or social inconvenience. Secondly, it means that any form of contraception used will not be physically harmful to either spouse, and will not involve the abortion of a fertilized egg. Finally, the decision to utilize birth control, as well as the decision to have a child, must be a mutual one between both wife and husband."
This seems like a reasonable approach to birth control. So why do the Orthodox and RC churches have such a differing perspective?
