Mary and Joseph were faithful Jews who obeyed the Law of Moses. Jewish Law prescribed that two ritual acts needed to take place for a firstborn son. First, the mother of a newborn son was ritually unclean for seven days, and then she was to “spend thirty-three more days in a state of blood purity” (Leviticus 12:2–8). During these forty days she was not to “touch anything sacred nor enter the sanctuary till the days of her purification are fulfilled.” For this reason, today’s feast has at times been called the “Purification of Mary.” Second, the father of the firstborn son was to “redeem” the child by making an offering to the priest of five shekels so that the priest would then present the child to the Lord (see Numbers 18:16). Recall that the firstborn male of all the Egyptians, animals and children, was killed during the tenth plague, but the firstborn males of the Israelites were spared. Thus, this offering made for the firstborn son in the Temple was a way of ritually redeeming him in commemoration of protection during that plague. Since Jesus was presented in the Temple for this redemption, today’s feast is now referred to as the “Presentation in the Temple.”
