Apparently you put your hand under it and it dispenses a few drops, like the automatic soap dispenser in public restrooms. No visible body in sight of, you know, water. No plunging of your hand into the baptismal waters. Just a bit of auto-dispense.
It seems to me that if we’re in a pandemic situation so dire that we aren’t able to use holy water in any meaningful way, then we just shouldn’t use holy water. We’ll survive. And then, someday, when we’re ready, we can once again have huge fonts with lots of water that communicate something meaningful to us about God’s abundantly flowing grace.
