Re: mikveh/mikvah -
Yes, Jewish women used to go to take ritual baths after their cycle was done for the month, as a sign that they were done with being sequestered in certain ways during their cycles, and also done with resting from certain kinds of work. There were special prayers involved.
A different sort of purification was done 40 days after childbirth, which is why we have the feast of Candlemas (aka the Feast of the Purification of the Virgin Mary) on February 2. This is also the source of “churching” blessings done on pregnant ladies when they start coming back to Mass.
When it comes to Jewish/Mosaic Law, it’s not quite right to say that it’s a case of “ritually pure” or “ritually clean” versus “ritually impure” or “ritually unclean.”
There were some very good things you could be doing that made you “ritually impure,” for example, like close contact with God. Helping birth a baby and helping bury a body would both make you “ritually impure,” because they both were contact with blood. So you had to make yourself ready for contact with other human beings afterward, because blood was a big thing (and obviously, so is God!).
So it might be better to think of “impure things” as “things that temporarily set you apart from other Jewish people, unless they are being set apart by the same thing.” Good things, bad things, all the same category of apartness.
And yes, archaeologists have found a mikveh in Nazareth, just like they’ve found one in almost every Jewish village and town. It was one of those basic things that you had to have.
Here’s
a story from the Times of Israel just the other week about finding a mikveh that was probably used by St. Elizabeth and the Virgin Mary, in Elizabeth’s village up in the hill country of Judea.
There’s also some interesting info about vessels used for ritual purification, which of course ties into the vessels that Jesus had the servants use at Cana for the water that He turned into wine:
John 2:6-7 –
“Now there were set there six stone waterjars, according to the manner of the purifying of the Jews, containing two or three measures apiece. Jesus says to them, “Fill the waterpots with water.” And they filled them up to the brim.”
(Stone jars weren’t just used for purifying women after their cycles, but that was one of their uses. They would also have been used for washing all the diners’ hands before eating the meal, and for purifying the bride and groom before the wedding and after their consummation. So it’s yet another way that women and men are both “there” in the Cana story.)
