The pattern of teaching the bible in churches no doubt constitute church doctrines some of which are geared towards giving church members false hope of prosperity and freedom from poverty. For instance, all pastors on pulpit quoting scriptures are not interested in you church members knowing the nitty gritty, the comprehensive understanding of what the scripture is all about, but their aim are always to let you know that if God could do all those great miracles in the bible, certainly he will free you from poverty, shame miraculously.
Now, that is what is call a false gospel.

Below is a screen shot of a CRK curriculum thought in schools. You can see how the content of the bible is arranged and every topic of the lesson are no doubt exactly what is in the bible.
No false hope prosperity,
No rapture of the saints(another confused fictional doctrine thought in church)
No personification of bible characters(For instance : saying the blessings of Abraham are mine)

All lessons are for knowledge
Understanding
Knowledge
Understanding
Knowledge
Understanding.

Note : there might be fallacies in CRK teachings in schools but it is clear that those fallacies are not well pronounced, frequent compared to church doctrines.

The question now is : What CRK is offering to the society by teaching children and what the church is doing on pulpit, which is better?

Yes
