I find it interesting that this question is "...sacred" and not "...the sacred." I have often heard the words "the sacred" used to talk about a way of experiencing God as person, force, object, etc. Without the definite article, it does bring in a new element. The word sacred is defined as "something connected with God [or gods] or dedicated to a religious purpose and so deserving veneration." In the dictionary I used, it is an adjective and not a noun (proper or otherwise). So, this question has a bit of a different slant than it could.
