I know what I think they are but my list is longer than 2. Here are my top 3.
1.There is only one "God" probably a shit ton of arrogant scientists (creators) out there fucking with us and our DNA.
2. Only the preacher can commune with said "God"
3. All humans must follow the same rituals
Number 1 is eternal life,
First all atoms remain alive after we die and that is just fact. Then one must let the mind think. So your new to heaven and the first year is meetups with the ole family, you are not tired, hungry, thirsty and so on. After the next ten years you have done a lot and now you are reaching 1000 years, 10,000, 1,000,000 and just think this never ends. Now if you believe you arrive in heaven with the soul you currently have then you use time to evaluate your world, Good luck with eternity my friend, I would ask to killed somehow if I was still thinking for eternity.
Lie 1. God exists and you must believe in what we say otherwise when you die you will burn and suffer for all eternity.
Lie 2. We are your only path to God and you must keep giving us your freedom, money and mind so that we can make sure God loves you and doesn't make you burn etc.
Being a former church goer for most of my life, I would say the most detrimental teaching for me was the beginning phrase...."You'll burn in hell if you (insert sin here). The second has to be how the church teaches contradictory lessons. And how they twist the Bible to fit their agenda.
I would say:-
In other words 'If you are a man or woman of god you are a good person, by definition' - this leads to all sorts of nasty stuff. You can do anything, however foul, if you devoutly do it in the name of god. Whatever crime you commit, as long as you repent and pray you should be instantly forgiven. Anyone 'not of the faith' is, by definition, someone of lesser virtue, of lesser value - someone to be despised.
There is nothing more disgusting, more corrupt and more foul than abusing the trust and inquisitive curiosity of children by undoctrinating them. Let the kids grow up with healthy, open, enquiring minds - THEN present them with the bible and see how they feel about it.
