In fact, it can dispense both with the philosophical thesis of the immateriality or indestructibility of the human soul, and with the theologicial thesis of a miraculous corporeal reconstruction of our person; theses, the first of which is altogether foreign to the religion of the Bible, and the second absolutely opposed to reason." Second, "the idea of life, as it is conceived in this system, implies the idea of a power, an operation, a communication, since this life no longer remains, so to speak, latent or passive in God and in the Word, but through them reaches the believer. It is not a mental somnolent thing; it is not a plant without fruit; it is a germ which is to find fullest development." [1] [1] "History of Christian Theology in the Apostolic Age," vol. ii. p. 496. If we are asked to define more clearly what is meant by this mysterious endowment of Life, we again hand over the difficulty to Science. When Science can define the Natural Life and the Physical Force we may hope for further clearness on the nature and action of the Spiritual Powers. The effort to detect the living Spirit must be at least as idle as the attempt to subject protoplasm to microscopic examination in the hope of discovering Life. We are warned, also, not to expect too much. "Thou canst not tell whence it cometh or whither it goeth." This being its quality, when the Spiritual Life is discovered in the laboratory it will possibly be time to give it up altogether. It may say, as Socrates of his soul, "You may bury me--if you can catch me."
