“And God saw that the light was good, and God separated the light from the darkness.” Separation is an important concept in the Biblical view of the cosmos. Distinction is for the sake of the whole, as light and darkness are both good in their created relationship to one another. Separated but bound by their distinction, they create order, cosmos; mixed, they create confusion and chaos, at best dull grey. We should be attentive to this reality throughout the Bible: Israel is separated from the nations, but this is for the sake of the nations themselves. Similarly within the Church, religious and clerics are separated from the laity, but not in judgment on the laity or because the laity are unimportant, but precisely because both are needed to recognize the beauty of the other.
Lord, help me to imitate You by separating my thoughts, dividing them between light and darkness. May the Light Who enlightens every man rule over the day and over the night, and separate light and darkness upon the earth, that is, in my human nature.
