Postures of the Mass
During Mass we assume different postures: standing, kneeling, sitting, and we are also invited to make a variety of gestures. These postures and gestures are not merely ceremonial. They have profound meaning and, when done with understanding, can enhance our personal participation in Mass. In fact, these actions are the way in which we engage our bodies in the prayer that is the Mass.
Each posture we assume at Mass underlines and reinforces the meaning of the action in which we are taking part at that moment in our worship.
