Praying by candlelight is basically how all the saints in the world prayed, at least before the last 80 years or so. There is nothing specially holy about it, but knowing that I am in the same misty, foggy din that they experienced their many visions and trials in… well, it’s familial. Sitting in the darkness of a power-outage with only one candle in the middle of the room really illustrates our Lord’s “light of the world” teaching!
I’ll be setting up a tiny home altar soon, with just one candle on a high stand in the middle standing over a cloth. On it I’ll keep my rosary and above the candlelight shall be my crucifix; to the right of the crucifix an icon of our Lady kissing the Christ-child, and to the left of the crucifix an icon of the Ascension or Resurrection. All three will be arranged in a triangle, so the Annunciation is in Mary, the Nativity is in Christ in the rightmost icon - the Crucifixion in the crucifix - the Resurrection and Ascension in the leftmost icon. The whole life of our Lord will be there in trinitarian form above the small, weak lighted candle that is my soul. How the events of That Life shall tower over my little light!
