I guess I should have said, “The point of Good Friday services is to remind us of what occurred on that day”.
You can agree or disagree whether or not it’s a good idea to remember the Sacrifice Christ made on Good Friday. I don’t care. The point is though, for that kind of service, on Good Friday, it’s perfectly acceptable to pray, “lead us from darkness to light” because that’s exactly what Christ did when He died on Good Friday. He descended into the grave, surely a “dark” place, and then proceeded to destroy our slavery to the grave, thus leading us to “light”.
But again, please don’t let me stop you if your intention is to blast the Pope. Even if he doesn’t deserve it. Which he doesn’t, if one views this situation objectively.
