Why do CEF and GTU carry such a premium over Net Asset Value?

"In the Incarnation the whole human race recovers the dignity of the image of God. Thereafter, any attack, even on the least of men, is an attack on Christ, who took on the form of man, and in his own Person restored the image of God in all. Through our relationship with the Incarnation, we recover our true humanity, and at the same time are delivered from that perverse individualism which is the consequence of sin, and recover our solidarity with all mankind."
Dietrich Bonhoeffer
