Every Catholic Church has an altar lamp. Mounted or suspended near the tabernacle, it remains lit at all times of the day or night, signaling Christ’s eucharistic presence within.
Given its ubiquity, of course, the lamp isn’t something we usually focus on, especially when the sanctuary is well lit for Mass. We might glance toward it in an unfamiliar church, especially if the tabernacle isn’t immediately visible, but then we tend to forget about it. After all, it’s meant to direct our attention to God, to His presence in a holy place, not to hold our eye in itself.
But last week, when I stepped inside Mary Help of Christians Basilica outside of the scheduled liturgical times, most of the lights were out and the church was dim and quiet. And in the low light of that space, the small red flame was impossible to miss, marking the alcove where the tabernacle waited. And even though it told me what I knew, the lamp, its vividness in the dusk interior, was somehow still a pronounced comfort, straight through the dark.
The fact is that sometimes, even though we believe, we can’t see clearly. Sometimes we can’t make out the tabernacle we know is there. When the dark obscures God’s presence in our lives, we may not feel consolation or hear answers, but God never leaves us alone. The altar lamp is there to make explicit what we know by faith — and to remind us, in the very act of this reminding, not only that God, Emmanuel, is here with us but also that He speaks signs of His presence in humble, common, and continual ways we often take for granted.
The altar lamp in Mary Help of Christians Basilica, like the altar lamp in every Catholic Church around the world, burns faithfully. Our monastic sacristan, Br. Gabriel, replaces the candle each time it burns low, and in doing so, he not only maintains this gentle sign of signs but also embodies it by his watchful care. His patient service, too, becomes a reminder.
In the same way, your Christian witness – even in the smallest, most ordinary things you do to remain faithful to your families, your friends, and those God has placed in your life – are signs of His presence. You won’t often know when these lamps cut through the dark of someone else’s struggles. But they do.
May God give each of us the grace to recognize the many signs of His love, His presence, and His faithfulness in our lives. May He give us the grace to be these signs for others. And may we always rejoice in things visible and invisible.
