@maxdancona,
I understand where you coming from. And I agree. There is a great deal of confusion when it comes to the many and varied teachings of the thousands of sects claming to be Christian. But this is not because of what the Bible teaches. Rather, what we are seeing among the many churchs is a rejecting of what the Bible really teaches in favor of traditions and human preference. And although many try to pick out various scriptures to support their view, when a serious examination is done it's revealed that it in fact the Bible does not support their view. Take for example a teaching that has been in existence for many years but has not support in the Bible, forbidding priests to marry because this could somehow interfere with their relationship with God. Because of this teaching there have been all kinds of problems that have resulted. When examined in the light of the Bible however, this teaching actually goes against what is taught in the Bible. Note this point found in the book of 1st Timothy chapter 4 verses 1 - 3 the Bible's view of forbidding persons to marry.
(
1 Timothy 4): However, the inspired utterance says definitely that in later periods of time some will fall away from the faith, paying attention to misleading inspired utterances and teachings of demons, 2 by the hypocrisy of men who speak lies, marked in their conscience as with a branding iron; 3 forbidding to marry, commanding to abstain from foods which God created to be partaken of with thanksgiving by those who have faith and accurately know the truth.
If you note the apostle starts out by saying that some would "
fall away from the faith". As a result there would be hypocrisy and false teachings promoted. One of which was the forbidding to marry along with telling persons that they couldn't eat certain foods. Really, in the light of what the Bible teaches, any church that chooses to promote this is in reality going against what the Bible really teaches in favor of a false doctrine. Or as it is referred to in verse 1 "
misleading inspired utterances and teachings of demons."
To your point that one must use their brain or mind, the Bible agrees completely with you. Note how the apostle Paul made this clear in the book of Romans chapter 12 verses 1 and 2.
(
Romans 12) Consequently I entreat YOU by the compassions of God, brothers, to present YOUR bodies a sacrifice living, holy, acceptable to God, a sacred service
with YOUR power of reason. 2 And quit being fashioned after this system of things, but be transformed by making YOUR mind over, that YOU may prove to yourselves the good and acceptable and perfect will of God.
So really, the problem isn't with the Bible, but is has to do with people not wanting to use their power of reason when it comes to various teaches. And in other cases, many are just not willing to accept what it teaches and so they create their own.
