They are not supposed to have vices in the first place. Preachers who have vices are actually low, movies and dramas made people believe it is actually high. Either way, Christian Preachers who still actively seek their vices shouldn't be trusted, regardless if they're doing it in secret or not. 😝
Also from what I've read in history books, Christianity in Korea was originally centered in Pyongyang, the capital of Korea before the war. When rumors about the North's plan to invade the South, it started a mass exodus of Christians from Pyongyang. Only few (in the grand scheme of things) native Christian Koreans chose to migrate/escape to the South. Christianity was in major decline because the majority of them escaped abroad, and the missionaries returned home, and many Koreans got stuck in the North (many of them were Christians).
It took decades after the ceasefire before Christianity started to regain a foothold in South Korea. The South wasn't the center of Christianity in Korea. So, maybe, wives were the main catalyst for Christianity's foothold in the South but it was more likely because most of those Christian Koreans who escaped to the South were women, wives, and children; and the South even before the war, was heavily into Confucianism and Buddhism, and they're often men too.
(It was actually interesting, because before they were divided by ideologies, they were already divided in religion. Christianity was very strong in the North but very weak in the South. In a way, it makes sense because Christian missionaries often start in the Capital before they visit the far flung provinces. Yet, it took decades for Christianity to take hold in the South after the ceasefire; which points to other reasons, like the reign of Confucianism and Buddhism, as well as, the possibility of deep distrust on Christianity.)
Again, just based on what I've read.
