The Orthodox are also quick to say they are the "pure faith", but they cucked as fast as other denominations! The heaviest resistance I see is actually from American Protestants.
There’s an old fable about St. John Cassian and St. Nicholas. St. John walks up to God one December day, clears his throat, and says, “Father, there’s something I’d like to talk to you about. People are trying to get ready for your birthday, and they keep getting distracted by St. Nicholas.”
“Does that bother you?” asks God.
“Well,” says St. John, “I get that we celebrate his feast on December 6th, because that’s the day of his repose. But we also celebrate his birth in May, the translation of his relics in July, and his commemoration every Thursday! Meanwhile, my feast on February 29th only comes once every four years.”
“And?” God asks.
“I don’t think it’s fair,” said St. John Cassian. “I keep my garments clean, and turn aside from worldly things to focus on the heavenly. Meanwhile, St. Nicholas is always running off to help anyone on earth who asks, and coming back to heaven all covered in mud and filth.”
“Let’s see what Nick thinks about this,” says God. “Nicholas! Come here!”
After a while, God calls again. “Nicholas!”
St. Nick stumbles through the door, dripping from head to toe. A puddle begins to form beneath him on the floor of God’s throne room.
“What were you doing?” asks God.
“Sorry it took me so long, Father. A drowning sailor asked for my help so I had to swim him to safety before I could get here,” says St. Nicholas.
God turns to John Cassian. “St. John, do you go down to earth when the Church militant asks for your help?”
“Of course not, Father,” says St. John, “I have laid aside all earthly cares.”
“Well,” says God, “That’s why they remember of St. Nicholas so often, and you so rarely.”
In the late 19th century, Vladimir Solovyov interpreted it like this: the Russian Orthodox Church was St. John Cassian, spotless with doctrinal purity. And the heterodox Christians of Western Europe were St. Nicholas. Though their garments were soiled with incorrect doctrine, were doing much to help people and make earth more like heaven, even while the Russian Church was turning a blind eye to the cruelty of the Tsars and Russia’s system of serfdom. He saw a pressing need for reunion between East and West, for Orthodox to show the Western world the unchanging teaching of Christ, while the West could share with the Orthodox their drive to apply Christ’s commands to society.
For us to merely know what's true is never enough. Like St. James put it, “even the demons believe, and shudder.”
