Hello Bob,
Headcoverings and organ music? These are not doctrinal. Our doctrine has not changed.
Perhaps it would be helpful to look at the RC explanation that there is a difference between discipline and dogma. We don’t normally refer to those terms but it could apply.
What you are describing is a reflection of Economia. No slippery slope here!
Likewise for the issue of contraception.
We have always taught that abortion is murder, and any means which will cause the death of a zygote is killing, whether chemically or mechanically. These are not means to prevent pregnancy but to terminate it. Some pills could have such an effect, and would be forbidden.
Other methods are not necessarily ruled out, it becomes a pastoral matter while the motivation of the couple (and the spiritual state of each) is taken into consideration. An important point is that the pastor is usually involved in the process of discernment, and the faithful do not have a sense of abandonment or alienation from the church over the subject. Good counsel is provided and the family remains plugged-in to the spiritual life.
BTW, NFP (the rhythm method) is often the method of first choice, but barrier methods are not thereby automatically excluded. And Orthodox have an enormous number of standard days per year of fasting AND abstinence, which includes refraining from sexual encounters (I think this is generally unknown in the RC).
Holy Orthodoxy is rightly reknown for it’s natural stubborn conservatism. So this is not a matter of liberals undermining church teaching, it is well thought out. There is no conflict between traditional church attitude and teaching and the small measures of economia shown.
This might be contrasted with the large numbers of young RC who willfully reject their churches teaching, receive no spiritual counsel and often (even usually) fall into the trap of using an abortifactant method! This may be because the only real advice they receive comes from MD’s and friends, who are more interested in the material wellbeing of the couple than their spiritual wellbeing. Some couples eventually develop feelings of alienation from the church and stay away. Others must deal with the anxiety and hypocrisy of being “cafeteria Catholics” if they choose to continue attending and taking communion. All of these results can be extremely damaging to the faith community in the long run.
