pixie i am not disagreeing with you or chad. however the biggest cause for people believing in these false doctrines is one lack of knowledge, that is also in the bible and also the lack of confrontation to false gospels.
when jesus saw such things throughout the gospels he directly and immediatley confronted it in the open to teach us the truth that we will not fall into these things. where has this gon. theology has taught many that confrontation is judging and wrong. this is what many of the churches believe in these days. yet we see all through out scripture where wrong was confronted, even by the apostles.
it is like a child stealing a peice of gum from the store. if it were your child would you just say oh it was just a peice of gum and your little so it was cute. i wouldnt if it were my child i would correct him not because i hate or dislike or want to judge my child but because i love him and i want him to grow up right. the same is with us staying silent to brothers and sisters in christ and those that claim to be brothers and sisters in christ.
i am not writing this to start an argument, rather because it is the truth and the word of god.
