Trying to find the name of a movie I feel asleep to
Looking for a movie or possibly TV episode, likely watched on Tubi or Pluto TV. A blonde female scientist/professor gives a lecture in class, something about comparing in nuns to prostitutes. A student is secretly recording her. A monsignor walks into the classroom and the students show him respect/bow their heads. He asks what the lesson is about, keeps calling the professor “madam,” and argues with her about her donor list. She asks if she should dismiss the class, and he yells for the students to stay and be quiet. She says or strongly implies she does not believe in God. Later at home, her daughter is embarrassed and asks when this is going to stop because the whole town is talking about her and saying she's the Antichrist.
There is also a subplot involving an old woman connected to time travel. Someone leaves a note on the old woman’s door, and later people say the old woman vanished. Her name might be Margaret Barlow, Margaret Barrow, Margaret Bellows, Margaret Harlow, or something close to that, but I’m not certain. The movie may involve a “God problem,” science/math, atheism, or proof against God.
