I've had a hard time trying to find something I would find disagreeable in the Orthodox Church. The only thing that comes to mind is the allowance of divorce but I don't know every angle how it's addressed. The RC allows for annulment in certain circumstances but I hear even that is very difficult. Maybe divorce in Orthodox Church isn't as easy as some RC's make it sound.
When I look back at the issue of divorce in one Church or the other, personally I would not ever pursue it so I don't really care knowing more about it. My wife and I made a vow before God that, roughly translated, included 'till death do us part'.
Some say I'm just looking for greener pastures but in my view I'm just looking for some grass. Most of all the grass in my field seems to have turned to chaff.
Divorce is NOT taken lightly in the Orthodox Church... and yet out of LOVE, the Church wishes the faithful to live in joy, peace and good health... and for couples to help each other (and their children) on the road to salvation.
However, sometimes one of the individuals falls short of expectations... they break the bonds of marriage through immoral behavior, or the husband (or wife) tortures the other - physically or mentally... or they fall into an addiction (drugs, alcohol, porn, gambling...)... leaving the other person struggling and themselves falling into sin and away from salvation through frustration, anger, angst... Sometimes, one beats the other, bruising them, breaking bones, etc.
This is not how God or the Church wishes people to live. Therefore, for the safety of the innocent spouse, and their children, the Church, out of love and compassion, permits divorce...with due cause... and not because you found something younger or richer, etc.
Even so, it is limited to three times. A second marriage is permitted (shorter service), and a third... because things happen.... but, not a fourth.... which identifies divorce/remarriage as a habit not a necessity.
