As much as we would like a reunion between the Orthodox and Catholic Churches there are one or two issues that would need addressing.
THE STAND OF THE ORTHODOX CHURCH ON CONTROVERSIAL ISSUES
Rev. Dr. Stanley S. Harakas
**The church will permit up to, but not more than, three marriages for any Orthodox Christian. **If both partners are entering a second or third marriage, another form of the marriage ceremony is conducted, much more subdued and penitential in character. Marriages end either through the death of one of the partners or through ecclesiastical recognition of divorce. The Church grants “ecclesiastical divorces” on the basis of the exception given by Christ to his general prohibition of the practice. The Church has frequently deplored the rise of divorce and generally sees divorce as a tragic failure. Yet, the Orthodox Church also recognizes that sometimes the spiritual well-being of Christians caught in a broken and essentially nonexistent marriage justifies a divorce, with the right of one or both of the partners to remarry. Each parish priest is required to do all he can to help couples resolve their differences. If they cannot, and they obtain a civil divorce, they may apply for an ecclesiastical divorce in some jurisdictions of the Orthodox Church. In others, the judgment is left to the parish priest when and if a civilly divorced person seeks to remarry.
(I don’t know if this is the same as an annulment in the Catholic Church nor do I know how many annulments a person may have in the CC. So this might be moot)
The Orthodox Church has a definite, formal and intended attitude toward abortion. It condemns all procedures purporting to abort the embryo or fetus, whether by surgical or chemical means. The Orthodox Church brands abortion as murder; that is, as a premeditated termination of the life of a human being.
The only time the Orthodox Church will reluctantly acquiesce to abortion is when the preponderance of medical opinion determines that unless the embryo or fetus is aborted, the mother will die. Decisions of the Supreme Court and State legislatures by which abortion, with or without restrictions, is allowed should be viewed by practicing Christians as an affront to their beliefs in the sanctity of life.
