Candlemass: On the procession and blessed candles

"We walk while we sing to God to denote that to stand still in the paths of virtue is to go back. The lights we bear in our hands represent the divine fire of love with which our hearts ought to be inflamed, and which we are to offer to God without any mixture of strange fire, the fire of concupiscence, envy, ambition, or the love of creatures. We also hold these lights in our hands to honour Christ, and to acknowledge him as the true light."

- Saint Bernard of Clairvaux
