It is more important for secondary educators (remember parents are the primary educators) to impart Truth than to assist their students in "feeling good" about Truth.
Do we not teach the truth of math and disregard how someone "feels" about it?
Please, please, PLEASE treat the souls under your care with the same respect when teaching the tenets of the Catholic Faith as you treat the minds of your students in other subjects.
Also, keep in mind that faith is not just a product of squishy "feel good about Jesus" exercises. It is also highly intellectual. The children can not only handle Truth, they crave it.
We all, including children, are in constant spiritual battle with the master of deception. Therefore, let us all don the armor of God.
