I never met Christians parents who assigned Bible verses to their kids for memorization and then punished them for not doing it.
We all taught our kids the Bible and Scripture and their minds absorb just fine by hearing over and over. Forced memorization regimes are not necessary. Regularly reading the word will do it.
I spent two years in a private school run by Baptists and we did do rote memorization of certain verses but we read the Bible through many times over the course of those two years so things with Biblical connotation just jump right out when you encounter them, it might not be word for word but you recognize it. I hated it then, and have issues to this day with certain types of Baptist, but it’s done right for me in life. There’s something else going on with the murder of this poor boy.
