Moltmann: fellowship and friendship as church reform

Moltmann ,"The Church in the Power of the Spirit: A Contribution to Messianic Ecclesiology p.317":

"The church will not overcome its present crisis through reform of the administration of the sacraments, or from the reform of its ministries. It will overcome this crisis through the rebirth of practical fellowship.... Fellowship in word and sacrament, fellowship in the profession of faith, fellowship in the institution and the  hierarchy, become lifeless and are petrified into formalities with which people can no longer identify themselves, if fellowship among the congregation’s rank and file is lost, and if friendship is not recovered from the ‘grass-roots.’”  Link
