Since the Great Western Schism, the Orthodox Churches drifted away from what the Church has taught on the indissolubility of the sacrament of marriage, which could be a hurdle greater to overcome than papal primacy in a hypothetical reunion, because it touches on a fundamental difference not so much about how the Church is considered but about the deposit of the Faith. Are there other such doctrinal differences?
Actually, Orthodox Churches never drifted away from what the Church has taught on the Mystery of Marriage…Jesus Himself gave a reason as to why divorce was permissible: Matt 19:9. The Orthodox have always recognized that marriage from the beginning was until death, but like Moses, the Orthodox Church has permitted divorce due to the hardness of their hearts.
Unlike in the Catholic Church today, there is a limit to the number of divorces and remarriages in the Orthodox Church. The Catholic Church, to be honest, hands out Annulments like candy and there is no limit on the amount of them for an individual. Nearly every couple who has been married in the Catholic Church, by a Catholic Priest in front of Catholic witnesses can obtain an annulment should they want one. I studied Annulments and specifically what can qualify someone to get one. The entire Dark Ages Western European world would have one because of their practice of marriage only to relatives - isolated towns frequently inbred - cousins, etc. especially Royal Families.
The problem with Annulments, unlike an Eclesiastical Divorce, is that the when the Catholic Church declares a marriage Annulled, they are saying that the marriage
never existed. Which means until the Annulment happened a Catholic couple thought they were married, yet they weren’t. Therefore, a couple who unknowingly have not “actually” been married, have in fact been living in sin…living with and having sexual relations with a person who is not your spouse is a Mortal Sin in the Catholic Church - meaning that if the person dies unrepentant, they will spend all eternity in Hell. That is some serious business!
Annulments are madness, especially the way the Catholic Church currently, frequently declares them.
There are by far, more Annulments handed out in the Catholic Church than there are Eclesiastical Divorces in the Orthodox Church.
The result to the children of these marriages ending - whether it’s is declared an Annulment or an Eclesiastical Divorce is identical - it is tramatic and forever leaves a mark.
At least a 2nd marriage in the Orthodox Church is approached with repentance and sorrow after Confession, rather than with joy as a 2nd or 3rd, 4th, 5th, 6th marriage or more (yet called the 1st marriage) in the Catholic Church.
My own father was a Catholic and before he died he was married 4 times - leaving children behind with each annulment. Had he been Orthodox, the most he would have been allowed was a total of 2 marriages after his first failed and then only if he would be granted an Eclesiastical Divorce - which is not easy to get - only certain grounds allow for it.
In the Catholic Church, all a groom or bride needs to do, is drink a lot of cough syrup before the wedding service that has alchohol in it, so that years down the road he can say he was under the influence of alchohol at the wedding and he or she would be granted an annulment.
At least within Orthodoxy a married couple has is secure in the knowledge that if they had a wedding in the Orthodox Church, they are married - they will not wake up 37 years down the road to find out they were never married after all. I have no idea how Catholic Couples can live with that type of complete insecurity about something which should be a basic given.
