wow. obviously, that part refers to human beings, descendents of Adam, who's sin causes them to need a savior.
Way to play the semantics card.
Oh, obviously it does. The problem I illustrated there, however, is that nothing is really simple when you boil it down to one verse, one quote, or one anything, really. If you take that verse and that verse alone, and discard all other context, Jesus is a sinner. Once you put it in the larger context, the verse becomes more clear in its meaning.
For Catholicism, the oral Tradition handed down from the apostles is on equal level with Scripture. It does not
contradict Scripture from their point of view, but it is equal in defining doctrine.
No one's disputing this. The problem with Catholics is that many of them think that this involvement entitles Catholicism to promote not only doctrine that's unbiblical, but also outright contradicts the Bible. Mary supposedly being sinless is one example.
There is scriptural evidence for apostolic succession with the whole "go forth and preach" and laying of hands stuff. The system that the Apostolic Churches have constructed is not something simple. It is extremely deep and complex and rooted in ancient history. They believe they are "entitled" to promoting those doctrine (which, in their view is not unbiblical), because as far as they see it, history supports their claims.
I, of course, am of the opinion that once you begin to look into history, the ideas of the Protestant reformation are not so solid as they seem to be at first glance. There is something more, and that something more was the first 1,500 years of Church history that many Protestant denominations have cast away.
