The Orthodox Church has retained the 7 Sacraments and Apostolic Succession. They do err in the fact that they do not submit to the "keeper of the keys(Peter and his successors) and they believe that one can get remarried even after the first one was sacramentally valid. In other words, they believe in divorce and remarriage.
So you are saying the Orthodox Church is honest in admitting they accept divorced/remarried people, but the Catholic Church has taken the high moral ground and doesn't allow it?
I had a friend back in the 80's and 90's who was a rabid Catholic, born and raised. We'll call her Philomena, a good Catholic saint's name, since that was her name! She told me a huge number of her family were priests and nuns. She was married with 5 children. Her husband was an alcoholic and an adulterer. He slept with my neighbour, who was not exactly pretty. (Philomena was pretty, I'll give her that!)
So, as things always go, he became abusive - mentally, physically and sexually. She prayed for him to "get saved." She knew the evangelical lingo, but she actual prayed for him to convert to Catholicism, doing the rosary constantly. He didn't get saved, went into rehab, was a nice guy for a week, back to drinking.
Finally, in desperation, she went to her priest. She wanted to remain Catholic, and she knew divorce would make her ineligible to take the Eucharist. So, the first thing the priest said to her was, "No problem, we'll annul the marriage." Say what? So, what does that make her legitimate 5 children? Illegitimate? I never got an answer on that.
So she dumped her husband. In the meanwhile she met a wonderful man, who had been studying for the priesthood. He asked her to marry him, and his mom told her not to do it. She accepted and within a few weeks, sold her home to move to where he lived. He asked her to loan him $10,000. She did and never saw him or the money again.
Then, she was instructed by her fellow nurses to do disgusting sexual things with multiple men. Which she did. She said it was not an issue, because she could go to confession before mass, and she would be wiped clean, so she could do it again the next weekend. I told her at that point, I never wanted to see or hear from her again. (Oh yes, I preached at her extensively, read her the relevant Bible passages, but she liked Mother Church and its deceit better!)
PS. I know not all Catholics are this immoral. But, the system of the Catholic Church is deceitful, it preys upon people and it is evil.
And just to impress you, my sister was at St. Peter's Basilica in Rome this morning, where she heard mass by the Pope. She also saw where "St. Peter" was buried. So, a long letter to her how Peter was never the leader of the church in Rome, it was Paul, and no one knows where any of the disciples or church fathers were buried. Which is as it should be - because then people don't go worshipping artifacts and idols. Instead they worship Jesus Christ, the living God!
