How many candles?

In Paul Turner's Blog by Paul Turner

Q:  Some people insist that 6 candles should be used on the altar at Sunday Masses because it is a Solemnity as indicated in the GIRM. However, GIRM 117 and CB 128 says 2, 4 or 6 candles MAY be used on or near the altar especially for Sundays and Holy days.  For a Mass celebrated by the Bishop, 7 candles should be used. Are 6 required for Sunday mass?
 

A:  GIRM 117 and CB 128 seem more interested in 2 candles as a minimum. The GIRM permits 4 or 6, and it says “especially” for Sundays and Holy days. But I agree that the word “or” leaves some flexibility.
