Dr. John Senior gives an engaging talk on the rise and nature of Christian Humanism, relating it to the ninth plague of Egypt, the plague of darkness, a darkness so thick you could feel it. All "isms" are a excessive adherence to something. Humanism is the excessive adherence to the "human". The Church can not be exceedingly attached to anything but God, and thus "Christian Humanism" while hoping to aid the faithful betrays them.
