Brad the point of difference in that instruction is formulated by MEN! o yea by MEN. And we are prone to errors so it becomes a subjective matter. But if you say the Doctrine of Christ, we all agree on that teachings. That is why if they believe on the doctrine to the purest then there is no problem at all.
But doctrine with instruction kana brad daghan mo lalis. Just take it this way. Christ never spoke about politics. Why did the Church feel to join politics? Its instruction not from God but from men who felt the obligation. I think its not scriptural so i don't believe on what they believe... gets?
If you say its FUNDIES yea thats the safest way to believe. Had Christian believe in the Fundamental doctrine, there will be no ADD-on to the Bible! and yea we can easily eliminate the cult. But because of compromise the RC are still answering question to an error up until today. INQUISITION? SEAT OF THE POPE? RELIGION MIXED WITH POLITICS.
As you have said mga brad, THERE IS NOTHING WRONG WITH CHRISTIANITY, ONLY THE PEOPLE WHO ARE SO CALLED CHRISTIANS. So the teaching is ok, but people wanted to contribute so it becomes a compromise.

hope you get my point.
