The Holy Eucharist is the most important of the seven sacraments because, in this and in no other sacrament, we receive the very body and blood, soul and divinity of Jesus Christ. Innumerable, precious graces come to us through the reception of Holy Communion.
Protestant attacks on the Catholic Church often focus on the Eucharist. This demonstrates that opponents of the Church—mainly Evangelicals and Fundamentalists—recognize one of Catholicism’s core doctrines. What’s more, the attacks show that Fundamentalists are not always literalists. This is seen in their interpretation of the key biblical passage, chapter six of John’s Gospel, in which Christ speaks about the sacrament that will be instituted at the Last Supper. This tract examines the last half of that chapter.
The doctrine of the Real Presence asserts that in the Holy Eucharist, Jesus is literally and wholly present—body and blood, soul and divinity—under the appearances of bread and wine. Evangelicals and Fundamentalists frequently attack this doctrine as "unbiblical," but the Bible is forthright in declaring it (cf. 1 Cor. 10:16–17, 11:23–29; and, most forcefully, John 6:32–71).
"Do as you wish; for we are Christians, and we do not sacrifice to idols."
