In this episode we read the Catechism concerning the three mysteries of the Eucharist. The Catechism also gives considerable evidence from Scripture, the teaching of the Fathers and declarations from church councils concerning the truth that Christ’s true body and blood are contained in this sacrament under the accidents of bread and wine. Additionally, we read several sections from the Summa Theologica concerning these matters. (ST. IIIa Q. 75. a. 1 and a. 5)
