Here is an excerpt of Muller's statement:
Again, I apologize if this seems blunt, but what I must say is too important to dress up in flowery language. The fundamental theses of Conscious Evolution are opposed to Christian Revelation and, when taken unreflectively, lead almost necessarily to fundamental errors regarding the omnipotence of God, the Incarnation of Christ, the reality of Original Sin, the necessity of salvation and the definitive nature of the salvific action of Christ in the Paschal Mystery.. . .
I do not think I overstate the point when I say that the futuristic ideas advanced by the proponents of Conscious Evolution are not actually new. The Gnostic tradition is filled with similar affirmations and we have seen again and again in the history of the Church the tragic results of partaking of this bitter fruit. Conscious Evolution does not offer anything which will nourish religious life as a privileged and prophetic witness rooted in Christ revealing divine love to a wounded world. It does not present the treasure beyond price for which new generations of young women will leave all to follow Christ. The Gospel does! Selfless service to the poor and marginalized in the name of Jesus Christ does!
