The revelation of Christian Science was seen by its Discoverer, Mary Baker Eddy, as consisting of two related parts: the discovery and the proof in demonstration. See Science and Health with Key to the Scriptures, p. 123. In a similar way, a grasp of the letter of this Science goes hand in hand with the daily living of it. The parts are connected. This Science and its practical manifestation are in tandem and may not be split. One aspect enriches the other. And this is proved through spirituality—through living as the very expression of God, Spirit, which Science reveals us to be.
There is a clear art to practicing Christian Science. It includes spiritual sense and intuition plus—highly important—holding the right connection between scientific metaphysics and its application. And spirituality, expressed not only in a love for the things of Spirit but in a love for humanity, moderates extremes—such as making so much of the metaphysics for its own sake that we tend to disregard its application to humanity. Or, on the other hand, having such an excessive concern for being practical with Science that we might half turn our back on the metaphysical and scientific demands that make its application effective.
Divine metaphysics is the backbone of the Science of Christ. But knowing metaphysics only as theory is emphatically not the all of being a Christian Scientist. We might be deep into metaphysics as the letter of Science but not immersed in the reality metaphysics points to. Or we may have lots of metaphysical thoughts yet have few benevolent feelings. We may have plenty of metaphysical notions but not many sturdy convictions.
