Many public schools no longer teach Christian education. It’s good to see a website like this: Request (based in the U.K.) designed to teach basic Christianity in the education system.
Depending on the school system, Christianity is rarely taught or not taught at all. Personally, I’ve lost hope in the secularized public education system in Canada. I would rather send my children to a public Catholic school where the Christian faith is still taught. Not every Christian family can afford to send their children to a private Christian school.
