Dagg on the Danger of Confusing the Kingdom of Christ With a Visible Ecclesiastical Organization

A quote from J.L. Dagg's Manual of Theology:

Wrong views respecting the nature of the Messiah's kingdom have been productive of much evil. The princes of this world crucified the Lord of glory because they could not recognize him in the person of Jesus of Nazareth, who came into the world to bear witness to the truth, and not to introduce his kingdom with the pomp which the carnal mind is pleased with. And Christ has been crucified afresh, and put to open shame, by his professed followers, because of their wrong notions respecting his kingdom. A visible ecclesiastical organization, distinguished by the observance of external forms, has claimed to be the kingdom of Christ; and its power has been extended and wielded by means far different than those which Jesus authorized. To banish this corrupt Christianity from the earth, correct views respecting the kingdom of Christ must prevail.
