ANSWER: There is but one self, not two. If this one self leans toward sin, it needs to be changed so as to lean toward holiness. St. Paul calls these two different states, the old man and the new. Hence some erroneously think there are two persons. When we speak of self-crucifixion we do not mean self-annihilation, but the change of the soul's gravitation from downward to upward, or from being self-centered to God-centered. The self which bears the full image of Christ does not need to be nailed to the cross.
