"Even a theology along the lines of the concept of apostolic succession, as is in force in the Catholic and the Orthodox Church, should in no way deny the saving presence of the Lord in the Evangelical [i.e., Lutheran] Lord's Supper."
Who said this? Joseph Cardinal Ratzinger in a letter to the Lutheran Bishop of Bavaria, Johannes Hanselmann in 1993.
It can be found in print in the volume *Pilgrim Fellowship of Faith: the Church as Communion* by (then) Joseph Cardinal Ratzinger. It is on page 248.
Thanks to Dr. Tighe for sending along this fascinating volume!
