Getting back to answering the topic question -
What particular Church can claim the most martyrs?
I refer all of you to a good and concise read of the originating Orthodox martyres who were the first and the oldest none imperially sanctioned priesthood that made sacrifices for the last 2000 years.
The Martyred Church: A History of the Church of the East. By David Wilmshurst. pp. xxi, 522. London, East & West Publishing, 2011.
Excurpt -
"The Church of the East is arguably the most interesting of all the Syriac-speaking Churches. Few outside the Middle East are familiar with it, yet between the ninth and fourteenth centuries the Church of the East was the largest Christian Church in the world, with dioceses stretching from the Mediterranean to Asia and China. The church has been harried and persecuted throughout its history. The tragic story of this `martyred church' is brought vividly to life in this impressive book."
The Assyrian Church of the East's greatest persecutors were not predominately unbelievers, but were other prophesying Christians who sought to first ostracize them and then proceed to vilify them before unbelievers in order for the unbelievers to do their bidding. Much martyrdom of the Assyrian Church of the East was cultivated by prophesying Christians who deep down in their hearts wanted them destroyed and gone.
One can see from its status for 1300 years as the largest Church who thrusted the Gospel into the hearts of the unbelieving enemies, who embraced them and did not harm them, then all of a sudden the same unbelievers who were peaceful and receptive to the Men of Nineveh were pushed to then punitively target them. The very collapse of the 3000 churches across China is not by the hand of the enemy, but by the puppet masters behind the emperors during the inquisitors of heretics during the Imperial Byzantine poltical power players, who made packs with unbelievers against the Men of Nineveh behind closed doors, unbeknownst to the Men of Nineveh.
Yet all things come around in full circle as God would have it his way, then the Balshavics came to equalize the score.
Karma ?
The two knights on God's Chess game are the Assyrian Church of the East and the Chaldanians who were one before the prophesying Christian agitators split them.
Anyway, now that we know that God is in control and not the standing empires with their armies, we should think deeply why God has chosen these two knights who are really one, to bring the game to a head before the mother of all martyrdoms.
Treat each other nicely please and learn from your fathers mistakes for heaven sake, because you really do not want to be a casuality of God in his grand master chess move to bring it to an end finale.
The knight is God's handy work (Isaiah 19:23-25), or at least believe the Son when he said the Men of Nineveh will come to condemn this New Testament generation.
Please learn from the mistakes of your fathers and don't do their mistake for heavens sake, otherwise something worse than communism is coming around the corner for your denomination.
