newtonian mechanics - Why do we say that the earth moves around the sun?


In history we are taught that the Catholic Church was wrong, because the Sun does not move around the Earth, instead the Earth moves around the Sun.


But then in physics we learn that movement is relative, and it depends on the reference point that we choose.


Wouldn't the Sun (and the whole universe) move around the Earth if I place my reference point on Earth?


Was movement considered absolute in physics back then?
