I’m not sure how this came up, but the story is the same over and over where Protestantism (especially of the Bible-alone variety) takes hold:
Here’s a good recent example:
Korea there are ~15 million Protestants, ~9 million are Presbyterians
in more than 100 denominations. –

The first Korean Presbyterian minister was Suh Sang-Ryun, who founded a church in Hwanghae province in 1884 –

It’s only been 131 years and 100+ divisions of the SAME denomination with no unity! Bible alone?!

It is scandalous to Christians and even worse to non-Christians.
Papal Visit That Thrills Catholics Is Unsettling to Protestants in South Korea

“The enemy king has appeared at the center of our nation!” the Rev. Song Choon-gil, a Presbyterian pastor, shouted during a rally of hundreds of Protestants who gathered a few blocks from the papal Mass on Saturday. Accompanied by a band, the evangelical Protestants sang hymns and danced, shouting that they were sounding “the trumpets of spiritual war” against the “idol worship” and “satanic forces” they said Roman Catholicism represents.
…
Competitive proselytizing, however, also created some of the problems now dogging South Korea’s Protestant churches. Some non-Christians are offended by Protestants who seek converts on Seoul’s streets and subways, sometimes shouting through megaphones that nonbelievers will be relegated to hell.
…
In a widely cited annual survey conducted in December by the Christian Ethics Movement of Korea, South Koreans selected Catholicism as the most trustworthy religion, followed by Buddhism and then Protestantism.
**** Sure, surveys are fickle and no indicator of long term sustainability, however, the reason is important ** (My note)**
The Catholic Church has suffered its own problems, mainly criticism that it has focused less attention on the poor in a country already troubled by a growing wealth gap.
Still, the church is more often associated with the downtrodden than are Protestant groups, which generally embrace capitalism wholeheartedly and are aligned with some of the country’s wealthiest citizens and most powerful political leaders. That alliance was especially pronounced under the former president, Lee Myung-bak, a Presbyterian elder and a former business leader; when he was the mayor of Seoul, he vowed to “consecrate” the capital to the Christian god. Catholic leaders, on the other hand, often played a visible role in left-leaning causes, some of which resonated with a public that is generally enthusiastic about capitalism but increasingly concerned about social inequality.
Choo Chin-woo, a local newsmagazine reporter who has specialized in covering the country’s churches, said Francis’s comments expressing concern for the poor and his criticism of capitalist greed had made clear the difference between the pope and the Korean leadership of both Protestant and Catholic churches.
“In the standard of the mainstream Korean churches today,” Mr. Choo said, “the pope is clearly a ‘commie.’ ”
