Not all attractions are for the whole family. Museum officials caution that kids under 14 may be too young to attend the special 3D viewings of the true, but graphic documentary When They Replaced “Christ” with an X!
Side note: Xmas is just as valid.
You have to understand that it is not the letter X that is put into Christmas. We see the English letter X there, but actually what it involves is the first letter of the Greek name for Christ. Christos is the New Testament Greek for Christ. The first letter of the Greek word Christos is transliterated into our alphabet as an X. That X has come through church history to be a shorthand symbol for the name of Christ.
