The custom in many churches of placing at the disposal of the public wax tapers known as votive candles, to be lighted before statues and sacred pictures in exchange for money offerings by the faithful, is open to serious objections. It might easily become what appears to be a superstitious usage, besides giving the impression that it is permitted for the sake of the money which it brings in. Moreover, the practice detracts from the decorum and cleanliness of sacred buildings, bespatters the floor, impregnates the hangings with smoke, and consumes good air. The practice must therefore cease. ... The reasons for this prohibition are to be explained to the faithful by the clergy, who will also remind them that a single Mass, heard with piety, and a single Communion devoutly received will bring down more heavenly blessings and favors than thousands of candles burned for days on end (Canon Law Digest, vol. 2, p. 375).If someone wanted a candle to be burned, the directive stated that he should buy one that would be used on the altar for Mass.
I never imagined I'd see a condemnation of votive candles: pretty unobjectionable, I thought. Even so, the statement does raise reasonable concerns. If today we didn't have votive candles, though, faith and piety would seem really cold, figuratively and literally--especially at shrines and pilgrimage sites. It's probably the most common way people show devotion....for better or worse.
Also, I wonder what "the hangings" were. I thought felt banners and that sort of stuff only came along in the 70s. So, my guess is that they are altar cloths. Take that guess with a grain of salt, though, since I have absolutely no knowledge of the typical decorations of a 1930s, Roman parish.
