What the Religious world FAIL to teach

There are so many religious churces that FAIL to teach various MANY things that are encircled around family. God created the family to be a UNIT that serves him. But, from observing various factors, other factors have taken man away from the status of being a husband to the wife or vice versa, which causes the family to be distorted. Is doing other things outside of the norm causing PROBLEMS within the family structure that is NOT apart of God's plan.
