Knecht, Friedrich Justus (1910). A Practical Commentary on Holy Scripture(en inglés). B. Herder. p. 410. Consultado el 27 de diciembre de 2016. «We keep a feast on the 2nd of February, forty days after Christmas, in memory of our Lord's Presentation in the Temple. This feast has several names. First, it is known as the Feast of the Presentation of our Lord Jesus. Secondly, it is called the Feast of the Purification of the Blessed Virgin Mary. But the usual and popular name for this Feast is Candlemas-day, because on this day candles are blessed before Mass, and there takes place a procession with lighted candles. Candles are blessed and lighted on this particular feast.»
