Ecumenical Acumen: De Lubac on the ecclesiologically limp-wristed
"We may avoid making a fatal dissociation of the visible and the invisible (as schism or spiritual anarchy so often do); we may be far from adopting the blurred concept of "evangelical catholicity" put forward by the liberal type; we may be equally disinclined to set in opposition charismata and the hierarchy, or spirit and authority. We may do all this, and yet still get onto the slippery slope- if we are not careful- via a dangerous distinction between the "visible Church" and the "Mystical Body" of Christ. Some thinkers have even found themselves led into this situation without actually so intending, through a lack of grip in their theological reflection."
Henri De Lubac, Splendor of the Church 91.
