Politically motivated miseducation that ultimately derives from the ruling class.
Thankfully, there have also been many heroic Christians: self‐sacrifice is, I would argue, the noblest of all themes associated with Christianity, and there have been some Christians who recognised that and put it into practice.
My favourite example was when the burghers of Regensburg gave their Jewish neighbours insincere baptisms to save them from violence (albeit violence from other self‐identified Christians, but still). Admittedly the New Testament might not have directly influenced their choice to be saviours, but I’d argue that they still demonstrated better Christian behaviour (and certainly better human behavior) than many Christians who adopt their faith simply for cultural or political reasons.
