Indeed we cannot call Godliness anything other than a radiation of light. In truth, no word, name or term can adequately be applied to Godliness. But since it is impossible to speak without words, we must call it by some name. However, we choose one that is somewhat less remote from Godliness than others. Light is the finest and most subtle of all physical phenomena, and accordingly it is less remote from Godliness than other phenomena. If so, the term “radiation of light” is the nearest we can choose. Even so, you must understand that we are not talking about a radiation of physical light. We are applying the term “radiation of light” only to give it some name.
