(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?
The passage does not speak to the question at all.
1 Corinthians 12:12-27
This agrees with me, one enters the mystical Body of Christ through baptism ("all baptized into one body", 1 Cor 12:13)
Ephesians 4:11-16
This passage speaks about the Mystical Body of Christ, but it does not speak abouit entering it in any particular way.
Romans 8:38-39
Speaks of external powers not being able to separate a believer from the love of God (there is a similar passage in John 10). Does not speak of a believer separating himself though loss of faith. However, we agree to the extent that baptism is an indelible seal or mark.
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?
Baptism requires a free-will commitment from either a parent or sponsor of a child, or form the baptizee himself if he is capable of reason. Baptism is ordinarily necessary for participation in the eternal life of Christ. Exceptions are possible when actual physical baptism with water is inavailable.
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
I disagree. The scripture is silent on whether Mary had physical marital relations with Joseph following the birth of Our Lord, however, those relatives that are mentioned by name in the Gospels are clearly children of Mary Cleopas and not Our Lady. The tradition of the Church teaches that Our Lady was ever virgin.
Do you disagree that the repentant thief on the cross experienced a complete acceptance in the paradise of God through his faith in Christ?
Not though faith alone: he professed his faith, repented of his sin, received baptism of blood through his suffering, and did the work of charity defending the innocently accused Jesus.
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?
Ordinarily, a sacramental confession is necessary from a priest, but otherwise I agree.
Do you disagree that the dogma of Purgatory is an un-Biblical doctrine?
The doctrine was formulated by the Church through her Teaching Magisterium relatively late, however, the fundamentals of the teaching: the necessity of the prayer for the dead and the need for purification after death is patristic. The scriptural basis for the doctrine is 1 Cor 3:9-15, Matthew 18:23-35, Matthew 5:26.
Besides, from experience I know that "un-Biblical" is sometimes used in the sense "not described in the Bible", and sometimes in the sense "contradicting things stated in the Bible". The Church teaches, and I beleive, that the absence of a teaching in the Bible does not invalidate it (e.g. the Holy Trinity is not defined in the Bible), and only contradictions with the patristic interpretation of the Bible count as invalidating factors.
Do you disagree that the dogma of the Immaculate Conception of Mary, as well as the purported Assumption of Mary are un-Biblical doctrines?
The dogma of immaculate conception derives from the past tense used by Archangel Gabriel in referring to Mary as "filled with grace (kecharitomene)" in Luke 1, but otherwise these are magisterial teaching.
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?
Non Catholics and non-Orthodox, and even unbaptized can be saved depending of their works and obedience to the law as revealed to them. Baptism is by the water in the name of the Father, the Son, and the Holy Ghost (Spirit). We welcome the Orthodox at the Catholic Communion in principle, even as we urge them to obey their bishops who disallow them to do so. We do not offer the Holy Communion to the other communities of faith because we do not have sufficient unity of faith with them, to which this discussion is evidence.
Do you disagree that the human psychological phenomenon known as "group think" can be a very deceptive, if not dangerous enterprise?
I agree, it is very dangerous to engage in group-think.
