The Christian churches and Christianity have nothing in common save in name: they are utterly hostile opposites. The churches are arrogance, violence, usurpation, rigidity, death; Christianity is humility, penitence, submissiveness, progress, life.
The Kingdom of God is Within You
When, at the age of fifty, I first began to study the Gospels seriously, I found in them the spirit that animates all who are truly alive. But along with the flow of that pure, life-giving water, I perceived much mire and slime mingled with it; and this had prevented me from seeing the true, pure water.
as quoted by Stephen Mitchell in The Gospel According to Jesus, appendix (1), p. 289
To regard Christ as God, and pray to him, are to my mind the greatest possible sacrilege.
