There are different names for the Church.  You can call it the catholic or universal church or you can call it the body of Christ.  I prefer the body of Jesus Christ led by the Holy Spirit.  It can be located at a certain place or better yet, it is inside of you.  We are temples of the Holy Spirit.  What the church is to be is holy as are we to be holy.  This differs from the common.  It is a holy place set aside from the world.
