I am not Roman Catholic.
I do not consider the Eucharist to be the literal flesh and blood of Jesus.
I do not talk with Mary.
I do not submit to the Pope or the Vatican.
Now tell me: Am I in full communion with Christ? Do you consider me “outside” His body? Do you consider me missing out on the fullness of life in Christ?
If I try to encourage others to believe as I do, about Mary and the Eucharist and about the RC hierarchy, do you consider me anathema?
that is your own personal interpretation. Lutherans, Anglicans, Catholics, Orthodox, Assyrians and Oriental Orthodox would disagree with you. Now, if you want to have us respect your personal interpretation of what you've read, why not respect our own interpretation of scripture?
isn't it arrogant to do otherwise?
Now, let's see what Martin Luther said about that: Who, but the devil, has granted such license of wresting the words of the holy Scripture? Who ever read in the Scriptures, that my body is the same as the sign of my body? or, that is is the same as it signifies? What language in the world ever spoke so? It is only then the devil, that imposes upon us by these fanatical men.
Jesus said to them again, Peace be with you. As the Father has sent me, even so I send you. And when he had said this, he breathed on them, and said to them, Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.
Am I in full communion with Christ? Do you consider me outside His body?
From the very beginning, the Body of Christ, the original Church, has taught the literal interpretation of Christ's command to physically consume his flesh and blood. You diverge from the original Church in this.
