Welcome Dark Rose, It's a shame you weren't out here in CA "back in the day".
That was the whole point behind Sanctuary.
Bands were out in the clubs reaching out to people but once those people came to faith many churchs just didn't know what do to with these "metal Christians".
Sanctuary was born out of that need. It was an open and accepting place for headbangers, punks, freaks or whatever other "interesting" culture one might belong to.
But it is Biblically sound. We believe the Bible is God's inspired word and we teach what the Bible teaches.
That I know of there is only one active Sanctuary today.
Sanctuary San Diego. Very big on goth and alternative.
