The entire Greek original has no capitalization, not even for personal names.
All disciples of Christ are part of the Body of Christ
Do you disagree that that body is formed through baptism? Because every time a conversion is described in he scripture, the convert is immediately baptized.
Do you disagree that through one's actions one can leave the Church? Examples are Simon Magus, Hymeneus and Alexander (1 Timothy 1), Ananias and Saphira (Acts 5), and we have to assume many more, as St. Paul in 2 Timothy complains that most have left him.
Thank you Alex. I responded to this unware that you did too. You are absolutely right.
Alex, I have already answered this one too. The point is that it is not enough to simply "adopt" Christ as your Savior. Gnostics, Jehova's Witnesses and Latter-Day-Saints claim the same thing. So, do Arians and Nestorians for that matter. There is a lot more to it.
(2) Do you disagree that through one's actions one can leave the Church?
MY TURN...
Do you disagree that accepting the Lord's invitation to life in the Kingdom of God requires an active commitment of the free will, irregardless of affiliations, acts, rites or rituals performed outside or in the stead of the active free will of man?
Do you disagree that Jesus had half-siblings (at least four brothers, and at least two sisters) that were the issue of the marriage of Mary by her husband Joseph the step-father of Jesus?
Do you disagree that the repentant thief on the cross experienced a complete acceptance in the paradise of God through his faith in Christ?
Do you disagree that Christians can be found in broken fellowship, and later found restored to favor and service by the extension of God's grace through the ministry of reconciliation, and appropriate expressions of repentance and forgiveness?
Do you disagree that the dogma of Purgatory is an un-Biblical doctrine?
Do you disagree that the dogma of the Immaculate Conception of Mary, as well as the purported Assumption of Mary are un-Biblical doctrines?
Do you disagree that Christians other than orthodox liturgists are indeed true believers, accepted of God by their baptism in water and Spirit with sincere faith in Christ; thus members of the Body of Christ and therefore welcome at the communion table in this life as they will be at the marriage supper of the Lamb?
Do you disagree that the human psychological phenomenon known as "group think" can be a very deceptive, if not dangerous enterprise?
