By doing this, they take any opposition to communion in the hand and equate it to opposition to Vatican II and by extension to being schismatic (as seen on freepnet by well-honed modernists.)
So they figure that since they cannot get you, they will get your children.
I can still recall my reaction the very first time I ever saw communion in the hand. I recall being completely stunned - not knowing whether to think the priest was a devil or something, or those who received the host on their hands were. Back then, for those of us who were taught over and over again that the whole idea was a sacriledge, it was a shocking experience to say the least.
We've come a long way baby, the practice of communion in the hand, sign of peace and the other novelties were supposed to more closely unite us with Christ - strange how it has accomplished the exact opposite right under of the noses of everyone.
