Lunar light is much more subtle, filtered, and indirect, and in that sense, more clarifying and not so quickly conclusive. Note that when God first divided light from darkness, God did not call it “good” (Genesis 1:3). At the very beginning of the Bible we are warned that we cannot totally separate light from darkness, or the two have no meaning. The whole of Creation exists inside of one full cycle: “Evening came and morning came and it was the first day” (Genesis 1:5). Separating them is apparently not good!
All things on earth are a mixture of darkness and light. When we idolize things as totally good or condemn otherness as totally bad, we get ourselves in trouble. Jesus simplifies this task by saying: “God alone is good” (Mark 10:18). Even the good things of this world are still subject to imperfection, wounding, and decay. I find it very hard to admit, but often tragedies produce much good fruit and good people.
Jesus is a “lunar” teacher, patient with darkness and slow growth. He says, “The seed is sprouting and growing but we do not know how” (Mark 4:27). He even shockingly says to let the good and bad seeds grow together until the harvest (Matthew 13:30). He seems to be willing to live with non-perfection, surely representing the cosmic patience and freedom of God, who is Infinite Love and Life that finally fills all the gaps. When you are God and you know you will ultimately “win”—because Love will always win—you do not have to nail everything down along the way. You can work happily and even effectively with “mustard seeds” (Mark 4:31) and with “the good and bad alike” sitting at the same table (Matthew 22:10).
