the reading is about the Samaritan woman. the Samaritans were in the northern kingdom and intermarried with others when they were conquered by the Assyrians. Thus, they were lesser Jews and considrred inferior to those from Judea. a question was raised about what baptism was then. iit was probably a purification ceremony. did Jesus baptise or was it left to his disciples. jesus may have not wanted to baptize because then they would have thought them superior to being baptized by others. it is amazing that Jacob’s well still existed 1000 years after Jacob. this well is not mentioned in the testament. his route took him thru Samaria which was unusual. why did Jesus do uncustomary things. Maybe to reach out to other people who might not otherwise be reached. it appears that Jesus had some sort of plan for his ministry. john is conveying a message to us and thus is part of a whole sequence about the power of water. he gave her leave to tell others about him as messiah while jesus frequently admonished them not to tell others. at the time this was written christian jews were not allowed in synagogues.
it was generally not acceptable for a rabbi to talk to a woman.
