There have been many Jєωs converted to traditional Catholicism. It is difficult to preach to anyone.
The Holy Spirit breathes where He will.
True, some Jєωs are ignorant, so when they are shown the truth, they may convert. We must pray for them as they face tremendous opposition from family and friends.
I have met several Jєωs who have converted, but their parents were not staunch Jєωs and had not raised them in the Jєωιѕн faith. However, once these inquirers were contacting Priests and were thinking seriously of converting, then things suddenly changed. Their parents opposed them, contacted a Rabbi, started taking their children to the local ѕуηαgσgυє, asked staunch Jєωιѕн friends and professors to preach to their sons and daughters, and in some cases, even sent their children to Israel to live in the Jєωιѕн communities and attend schools there. These parents suddenly got religion to the extreme.
The same scenario happens in Muslim families. Muslim parents who were not practicing Islam suddenly become extremists when a son or daughter tells them that they are taking catechism lessons to become Catholic. Those new converts could be murdered by their family or relatives in so-called "honor killings."
Do Jєωs also murder their family members who convert to Catholicism?
