Transubstantiation is a teaching, and also a Catholic doctrine, which says that, after a priest consecrates them, the bread and wine at the Mass become the body and blood of Jesus, whom Christians believe is the son of God. According to the teaching of transubstantiation, although the appearance, smell, and taste of bread and wine remain, the substances of bread and wine have really changed into the body and blood of Jesus.

Transubstantiation is also taught by some other Christian churches. view more...
