Hi Behe's Boy,
This will be my only post as I am neither a Calvinist, nor Roman Catholic. However, I must address some of the points you have made about Catholicism.
Behe's Boy said:
Christ may have ordained his apostles to carry on His mission - but that ordination did not included perfection.
The Church (that is, the pre-schism Catholic Christian Church) did not teach that any person is perfect, but that as a whole, the Church's doctrines must be correct. I do believe that if this was not the case, then the 'gates of Hades' surely have prevailed against the Church - after all, the Church remained strong for around 1000 years.
Behe's Boy said:
The pope is held in highest regard and considered perfect - I disagree and it is not scriptural.
In Roman Catholicism, the pope is not seen as perfect, but a special role is given to him as 'spokesperson' if you like for the Church. Eastern Orthodox do not agree with papal infallibility as defined by the Roman Catholic Church, as they believe it is unscriptural and against Church tradition.
Behe's Boy said:
Authority based on incorrect doctrine does not constitue apostolic succession. Sorry.
This is an interesting one. From a purely objective standpoint, the RCC does have apostolic succesion from Peter, whether or not its doctrine is correct or not. From the Orthodox perspective, after the Great Schism, the see of Rome effectively left the Church, so their apostolic succession is not valid. This would in some ways agree with your point, though the Roman Catholic Church believes that the Church is divided, and that it is still part of the 'Church'.
Behe's Boy said:
Mary is placed on equal footing with Jesus - incorrect.
This is not true. Mary, in Roman Catholic doctrine, was free from sin (like Jesus), but she was not divine (as Jesus was). This comes mainly from the Roman Catholic doctrines of the nature of sin, i.e. that we all share the guilt of Adam's sin. This is contrary to the doctrines of the eastern Church, which teaches that we are not guilty of Adam's 'Original Sin', although because of Original Sin, we are suspectible to sin due to the sinful world around us.
Behe's Boy said:
Praying to the saints is an incorrect practice and idolitary.
I am probably not the best one to explain this for you, but intercession does not equal worship. Catholics ask the saints to intercede in their prayer to God, in other words, to pray for them. This, in essence, is no different than asking anyone who is alive to pray for you. What would be idolatry is praying to the saints as though they were God, which is heresy, un-Biblical, and not Roman Catholic doctrine.
Hope this clears things up. If you have any questions, feel free to PM me
