"Liturgy and witness." Not liturgy as a means to witness or even, closer, the means to witness. For liturgy is an end, and the worship of the living God needs no other justification for creatures loved, redeemed, enlightened. But "liturgy and witness." Liturgy as witness and liturgy as formation, orientation, inspiration for the living of witness lives, both corporately as church and individually as members.
