Did you know there is such a thing as a “Jewish baptism”?
As with other religions, Judaism has various forms of washings and immersions in water. The priests often washed themselves in various ways before sacrifices and ceremonies in the Temple, and men and women had to undergo various ritual washings for other purposes.
Baptism for Converts to Judaism
One common form of baptism was for proselytes to Judaism. When a Gentile wanted to convert to Judaism, one of the rites of initiation was to undergo a ritual washing of purification called a Mikvah.
The Jewish Talmud, in the Mikva’ot tractate, states that when a Gentile wishes to become a Jew, he must be instructed according to the 613 commandments of the Torah, must be circumscribed, and must go through a Mikvah, that is, be baptized.
