Wet liberal that I am, I am a little confused by the enforcement of morality. Abortion is the greatest moral evil of our age. Divorce and remarriage is pretty ghastly too, civil partnerships are pretty damaging to marriage, fornication does not do it much good either.
As a wet liberal what do I do about it? I can rage about it in the pulpit, I can repeat the Church's teaching and refer to the Gospel, talk about how it damages society. I must admit I was a little shocked by some US clergy who were reported to ban Obhama voters from Holy Communion. The more nuanced reports of course were saying, "if you voted for him because he was pro-abortion".
Most of the women who have spoken to me about having had an abortion do so because they were so terrified, often after rape. Divorce and remarriage are so much part of the warp and weft of society, and again often the marriages that fail are built on foundations of sand, and are possibly capable of annulment. One or two of my parishioners have undertaken a civil partnership, and when I have stated my displeasure they assure me the relationship is one of companionship, inheritance and care in old age rather than genital activity. Fornication doesn't seem to be a serious issue for most of the graduates of our Secondary Schools, the vast majority of those who I have married in this parish were living at the same address, it could be only the dirty minded might imagine a premarital sexual relationship.
What do I do, what does the Church do?
The penance in the Orthodox Diocese of Athens for an abortion is a 7 years bar from Holy Communion, this is the canonical penance, and the confessor would also apply a salutary penance like fasting for an extended time, or some daily corporal penance.
Other Orthodox Churches would apply a penance of a year or a few months away from communion for fornication or homosexual acts.
Obviously we wouldn't want to apply this type of regime in the Latin Church, though I cannot think it fair to leave people confused as they obviously are.
