Eucharistic Revival

Why do we call the presence of Christ in the Eucharist a “mystery”?

The word “mystery” is commonly used to refer to something that escapes the full comprehension of the human mind. In the Bible, however, the word has a deeper and more specific meaning, for it refers to aspects of God’s plan of salvation for humanity, which has already begun but will be completed only with the end of time. The Eucharist is a mystery because it participates in the mystery of Jesus Christ and God’s plan to save humanity through Christ. We should not be surprised if there are aspects of the Eucharist that are not easy to understand, for God’s plan for the world has repeatedly surpassed human expectations and human understanding. Furthermore, any time that we are speaking of God we need to keep in mind that our human concepts never entirely grasp God. We must not try to limit God to our understanding, but allow our understanding to be stretched beyond its normal limitations by God’s revelation. ~ USCCB
