Steve is correct. There is almost never a zoning district for religious use, it is nearly always a permitted use in certain zoning districts.
Often cities are beginning to frown of religious buildings back in residential areas, as they invite traffic and parking hassles on the neighborhoods on Sunday mornings and a couple nights during the week. For zoning officials a church is most valuable for them as a buffer between different types of zoning districts - transitioning from retail, commercial or light industrial to residential.
Many municipalities frown on non-profits in general because they take property off the tax role. Technically this is illegal so another tag is put on that reality in the name of c.y.a. by the powers that be.
