Re: Votive/prayer candles...
We used to light votive candles everyday and turn of at night. One day however the wick got to close to the glass and cracked it. I discovered it before anything worse happened. My moms friend used to leave them on 24/7 but she doesn't do it no more because her 5 year old used to play with them.
It must be observed, however, that if the faith were endangered, a subject ought to rebuke his prelate even publicly.
