From their website:
At Weatherly, women are included in all areas of leadership, including deacons, teachers, preachers, and committee members. We value the many religious traditions within the larger community of Huntsville, believing that we need not invalidate another's belief to embrace our own. Weatherly also recognizes the liturgical heritage of Christendom. The paraments, clerical robes and stoles, and other liturgical symbols are a constant reminder that we stand in a broad, deep Christian tradition.
I interpret it to mean that although they are Baptists, they don't intend to trash the Anglicans, Congregationalists, Lutherans, Methodists, Nondenominationals, Presbyterians etc. I, personally, don't view gratuitous trashing of other denominations as part of mainstream Christianity. To me, that sort of idiocy is restricted to the lunatic fringe.
