It is not so much that Rome has lost it's lineage of apostolic succession but rather it has lost grace of apostolic succession by abandonment of the apostolic faith. ...
Still, I think that it can be argued that there are certain practices and teachings in apostolic times which have been abandoned by the Orthodox Church. For another example, take the teaching in apostolic times that slaves should be subject to their masters. Is it not true that the Orthodox Church has abandoned this apostolic teaching?
I wonder if this apostolic teaching was faithfully observed by the thousands and thousands of Irish Catholics shipped as slaves to the Americas. Did they smile obediently as their masters set their hands on fire or sawed off their heads?
"They came as slaves; vast human cargo transported on tall British ships bound for the Americas.
They were shipped by the hundreds of thousands and included men, women, and even the youngest of children.
"Whenever they rebelled or even disobeyed an order, they were punished in the harshest ways.
Slave owners would hang their human property by their hands and set their hands or feet on fire
as one form of punishment. They were burned alive and had their heads placed on pikes in the
marketplace as a warning to other captives."
