harrydavidson701l3 - This is the first time I've heard that such coloring pages are needed for school.

katherineturner - To be honest, neither do I. When my children went to school, there was no need for religious coloring books. After all, this is an ordinary school, not a religious one.
When my children were younger, I decided to introduce them to God. I thought that religious coloring pages would be perfect for this. Thus on https://matohash.com/blogs/news/free-bible-character-coloring-page-printouts , I found these coloring pages with biblical characters. I was engaged in teaching children religion. A little later, they began to go to a religious school, and there was everything they needed. In school, children do not have such a subject.
