A much more recent contribution is presented by Nicholas M. Healy in his book Church, World and the Christian Life (2000). Healy’s book is a fundamental critique of the general tendency in modern ecclesiology of working with concepts and models of the church, rather than the concrete church as it is. In his own words: In general ecclesiology in our period has become highly systematic and theoretical, focused more upon discerning the right things to think about the church rather than oriented to the living, rather messy, confused and confusing body that the church actually is.5
