In "Who are the Church," Joseph Komonchak gives us a concise recapitulation of the insights he has gained over a long and esteemed career as a scholar, historian and ecclesiologist. The book may be read as an invitation to Christians of whatever variety to think responsibly about the concrete reality to which the term "the Church" refers. Far from denying the transcendental element, Komonchak leads the reader away from an artificial transcendentalism and in the direction of discovering the authentically transcendental element of the Church as it exists in the concrete reality of the community of disciples.
