the Sacred & the Secular

I found this video this morning on a website called Work of the People that we at North Street often benefit from during our gatherings (it's 6:28 long, click on the picture to view it). Since both we and the website follow the Revised Common Lectionary, it's quite conducive to creating visual liturgy on a regular basis. This video reminded me of a number of conversations I've had in the last several months with different people and with myself over the difference (if any) between the sacred and the secular. There are a number of possible responses.

One says something like "everything is either sacred or secular." Another says that everything is sacred. Yet another might say something along the lines of "everything's secular without the presence of God." The most common response I've found in emergent circles says something like "there is neither sacred nor secular, time and space cannot be characterized as such."

I'd like to throw it out here for discussion. The most common response in the Church of the Nazarene seems to be that there are indeed times and places that are sacred, including worship gatherings, sanctuaries, the altar, etc., yet there's been a trend in the last couple of decades (with rapid development in the last 10-15 years) moving local churches out of the traditional sanctuary and into gymnatoriums and sanctatoriums. I don't necessarily know what this means (though I have a guess).

So if there is no sacred or secular, what does this mean about our worship gatherings (time and space)? How does the Holy Spirit play a role? What does the tearing of the curtain to the Holy of Holies imply? Does the Old Testament insistence on sacred-secular have any grounds today (i.e.: "stones of remembrance", the Ark of the Covenant, etc.)? What then does holiness with all of it's sanctified-set-apart understanding mean?

If it is appropriate to speak of the sacred and the secular, is anything secular beyond a movement into the sacred? How can something become sacred? Is this just a discussion to speak of beings (God and people) that cannot be applied to time and space?

Am I using the wrong terms?
