 In the Roman Rite, the 1960 Code of Rubrics prescribed the use of the red vestments for martyrs in place of the violet vestments previously prescribed on the feast of the Holy Innocents.The feast continued to outrank the Sunday within the Octave of Christmas until the 1969 motu proprio "Mysterii Paschalis" replaced this Sunday with the feast of the Holy Family.In the Middle Ages, especially north of the Alps, the day was a festival of inversion involving role reversal between children and adults such as teachers and priests, with boy bishops presiding over some church services.
