It’s not the candle itself, or a donation for same, that’s objectionable, at least not to me, but the “get out of jail free” card is a killer. That goes well beyond even the idea behind a memorial Mass, (I mean really, the graces from Mass (or DL) are infinitely more than “lighting a candle” but I digress), and it’s just plain wrong. If that’s the way the donation for a Presence Lamp is touted, then yes, IMO, it’s more than objectionable.
But I think you’re right: maybe we should just stay in the East (or Orient, as the case may be).
