The soul is like to God in its unity. As God is one in the Trinity of Persons, as Our Lord Jesus Christ possesses a supreme unity in His two natures, the divine and the human, so the soul of man has a supreme unity. The soul is one, as being a spirit, a simple, uncompounded, indivisible substance. It is not composed of different chemical elements or of different atoms like the body; so its unity cannot be broken by decomposition and death. The soul is conscious of the different and contradictory impulses which proceed from the flesh and the reason, from nature and grace, but these do not constitute two souls or two personalities. It is one and the same spirit that exercises the different classes of vital functions, thinking, determining, remembering. It is ultimately one and the same principle which receives impressions through different senses, and puts the different members of the body into action. The soul, although different in its character and origin from the body, yet coalesces into an extraordinary unity with it, forming one person with one activity and one responsibility. Remember that your soul is one and your only one. Its life here is its one and only probation while it is in union with the body. Your unending future depends on your one present life, and the result can never afterwards be changed.
