I would consider the Protestants making a spiritual communion with Christ as Catholics do. I find alot of the same sentiment and fruit of Christ in experience when sharing personal faith with Protestants.
What is different, though, is the reception of the Eucharist. The Eucharist has been the centrality of faith and worship since the beginning of Christianity. The great heresy was those who did not believe we are truly receiving the flesh and blood of Jesus Christ.
Afterall, the Lord knew the difficulty people would have in the Eucharist. So after feeding the 5,000, the Lord spoke to His apostles, disciples and followers about eating His flesh and blood. Many who heard this were repulsed and left Him. But the apostles did not. And Peter admitted where would they go…and that Jesus promised He would bring them eternal life.
Then in so many days, the apostles saw the entire context of Christ’s words at the Last Supper. And we are to ‘do’ Eucharist…‘Do this in memory of Me.’
So the implications of this is that we do not believe merely in words. The use of words has different meanings and responses to different people. Faith requires certitude.
Subsequently, the sacraments are non-arbitrary, non-issues of things of faith we do not continue discussing and arguing and debating. The Eucharist is the fulfillment of the Manna of Heaven in the desert, the image of Christ placed in a manager – an animal feeder.
Christ said He would always remain with us. He said He would give us His Comforter after He is gone, to teach us many things. So the Bible in itself is not the last source to find out more about Christ.
We find more about Christ through His Church, with the Apostles as the founders of churches. Christ is the cornerstone…a living Person, not just a word on a page in a book.
Scripture and Tradition – how we understand Christ from the Apostles and their practices, is how we define the Word of God. And the Word of God is the history of people…and when we become believers, our lives unite with all the people of faith in the Old Testament who lived way before us.
The Church and its history – the good and the bad, the virtues and the scandals – no different than the Jewish believers before us – have our history now as Christian…as John Paul II called us, we have our history now as fulfilled Jews. Our Vatican library reflects the final words of the Apostles that not enough books could ever be written about Him.
The Eucharist is the same part of God. We don’t debate. When we receive, we say ‘Amen’. The Eucharist is the key to living the celibate life, to enduring in the Cross, and accepting sufferings as redemptive.
