The Sonship cannot be perceived as partly sick, because to perceive it that way is not to perceive it at all. If the Sonship is One, it is One in all respects. Oneness cannot be divided. If you perceive other gods your mind is split, and you will not be able to limit the split, because it is the sign that you have removed part of your mind from God’s Will. This means it is out of control. To be out of control is to be out of reason, and then the mind does become unreasonable. By defining the mind wrongly, you perceive it as functioning wrongly. T-10.IV.3:1-7
Schucman, Dr. Helen. A Course in Miracles (p. 346). Foundation for Inner Peace. Kindle Edition.
The prime concept in A Course In Miracles is that God is the non dual Oneness of which we are a part if we choose to be aware of this. When we give up our separate egos we are filled with peace and bliss. When we remain separate, we suffer. Some of us want it to be both ways, to be one with God and also to retain our egos. This passage teaches that we can’t have it both ways. It’s one or the other. Either we are One with God or we stay in our ego. There is no such thing as being partly in our ego and also One with God. This idea, the Course teaches, is unreasonable and doesn’t work that way. It’s all or nothing.
In Unitarian Universalism some of us join together to affirm and promote the inherent worth and dignity of every person. This inherent worth and dignity comes from our Oneness with God and has nothing to do with our egos. Most people who call themselves UUs don’t seem to understand this. They continue to seek social justice for their egos and have forgotten what religion is for, the Atonement, healing the separation. Were they healed, social justice would become moot.
