Institutionalism in the Church

"There are real reasons for fearing that the Church might take on too many institutions of human law and then become like Saul's armor which prevented young David from walking.  It is always necessary to study whether institutions that were useful in the past are still useful today.  The only institutional element the Church needs is the one the Lord gave her; the sacramental structure of the people of God, centered on the Eucharist."

Pope Benedict XVI
