Looking at Luke 23:41-42, this article shows that the way Desiderius Erasmus treated the text did not do it justice. The dying thief who received forgiveness is not an example of "mere Christianity." The text shows that the thief knew a lot about Christ and His kingdom. The author of this article argues that the thief could have learned this from his childhood; thus, this text can be used to encourage parents in their parenting call.
