Transubstantiation

Transubstantiation is the belief that bread and wine become the actual body and blood of Christ during the Eucharistic celebration. This holy celebration began during Jesus’ Last Supper. It is written in the Bible that Jesus proclaimed both the bread and wine to be body and blood of Christ. To follow tradition this ritual has been a part of the Catholic Celebration from Jesus’ last day until present time. (This is contributed by CM)
