I think, certainly in the UK, people see Christianity as a form of life insurance, something that old people turn to in order to feel safe for their future. People have a very traditional view of what it means to be a Christian, and what church is like and see it is somewhere to go to when your mind is slowly deteriorating that gives comfort and peace in those final years. It is true that this aspect of Christianity exists, this is undeniable, but anyone who takes any of the teachings seriously will tell you that faith in the Christian God is far more complex, and far more relational than just a get-out-of-jail-free card.
If someone does something that is perceived as wrong then they tend to be punished. In the case of children, this punishment is usually administered as a form of discipline, teaching the difference between acceptable and unacceptable behaviour. They aren’t punished because of the thing that they did wrong, but because they are being shaped and moulded into the person that their carer wants them to be; it’s an act of love, or at least it should be. Most legal systems work on slightly different principles – their punishments are based on retribution, deterrence and rehabilitation.
