In relation to the process of digestion, the Catholic Church's teaching has been expressed in this way: "The substance of Christ's body is not subject to processes of digestion or to any chemical reactions. The qualities of bread of course behave in their normal way, undergoing a change as they are affected by digestion. Our Lord's substantial presence ceases as these qualities cease to retain those characteristics proper to bread."
