I have had very religious education. 4 years of mandatory religious seminary in high school (before school, started at 6am---I have lots of reserved feelings about those 4 years). Anyways, and then the unofficial little known fact of my religious studies minor that was required by my university. (14 credits worth, then all church they could squeeze into secular classes and on the weekends.)
I know A LOT of stuff going down...doctrine and historical.
You can imagine I've become a little burnt out. And honestly I only do the minimum to keep an ecclesiastical endorsement which is required to attend to school. So when they asked if I could work instead of sit through 3 hours of church and extra churhy' responsibilities that would go all night, I readily said yes ;)
When I arrived at work, they asked if I could accompany some patients to the non-denominational service. I was really excited because I'd never experienced anything outside of my own religion. Well the service actually turned out to be a vocal and well known Christian sect service (I'm not going to say which one to be diplomatic)
I tried to make eye contact with the other staff in the room because demographically everyone is the same religion here. Expect the patients and the preacher. No idea where they found the preacher.
Sunday's service was about not believing in fairy tales. To me that meant not believing in Shakespeare's A Midsummer's Dream, Harry Potter (though I would join if it was a church ;), or Disney (which probably could be considered a religion) haha.
He began that we should not believe in Allah...because he is a fairy tale.
Question #1 I'm definitely NOT Muslim. And perhaps it is my own paradigm or mis/understanding, but the Arabic-Engish translation of Allah is God. I assumed that Muslims believe in the same God as Christians, as Christians believe in same as the Jewish Elohim which translates to God. Did I miss that we all are not believing in the same God. And it made me a little sad to hear him say Allah is a fairy tale.

He continued to point out some very key points of the Religon of the staff. How our beliefs are all fairy tales. It made my stomach knot a little. You don't sit through four years of early morning seminary, and four years of university religious education, to have someone tell you your beliefs are fairy tales when we are all reading the same Bible.
Next he explained the Bible is perfect and we don't need to rely on anything other than the Bible.
Question #2 Fine, Fine, but then which one? There's like 50 different versions..King James, Gideon, Amplified Bible, Easy to Read Bible. And then all the copies that the Monk's were copying by hand until Gutenberg. Can we say... omg here is my statistics lingo...
Can we say with 100% confidence the monks and translators all had a small margin of error? There is no way to test our null hypothesis. Assuming we took all the earliest manuscripts and compared them to today's versions, (I doubt we would have a sample size larger than 30 for early manuscripts) (which is standard for conducting statistical research) even then we could not use a 100% confidence interval because our sample size would be so small.
I just don't think the Bible can be so perfect... But that's just me, not my actual Religous beliefs. And there are a lot of good books out there that teach just as many morals as the Bible.
Before the last question let me set the scene. The patients I work with have endured abuse so traumatic, their diagnoses are scattered throughout the DSM-5. Every adult in their life has failed them and I would even say that God has failed them. It is my understanding that we need to be positive and uplifting in every way.
What the preacher said next made my ears curl and I wanted to throw up. He quoted John 8:44 You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.

Question #3 This is not what I was taught, and this is not what my normal Christian friends believe. I woke up the next morning dead set on figuring out what was going on when Jesus said those things. Jesus was in fact, speaking to the Pharisees who denied Christ as a son of God. From my religious training, I remembered son's of perdition, people who deny Christ are deemed as followers of Satan. Perhaps that's what Jesus meant.
So it is my understanding that by believing in Christ you can be a child of God. I don't think that has to be pre-requisite to be a child of God though... Unless you go out and are super anti Christ I think you'll be ok.
Anyways...Crazy. All the staff had a good laugh about all the anti-stuff he said about us.
