That has been the traditional Catholic interpretation of that event. Every time Jesus addresses Mary as “Woman”, it is of great significance, as in the woman spoken of in Genesis, she who crushes the serpents head (Guadalupe).
The sword that Simeon prophesied would pierce her heart, that the thoughts of many might be revealed, happened at this moment. She was asked by the Savior of the world to be mother to the human race, who had just put her Son to death. Her heart was rent by this request. It is a profound mystery, the suffering of a perfect Christian, redeemed by Christ’s Grace in a special way, but not guilty of original sin or any personal sin. What is the value of that type of suffering when united with the saving passion of Her son?
