Yes, I was an SDA but that was a long time ago. There is an active SDA on this forum (Barry). He is a great guy, although I've not seen him post for two or three months. He is better qualified to help.
I was about 11 when some of my Roman Catholic family were visited by SDAs during one of their evangelising campaigns in my neighbourhood. We became SDAs and I was baptised in 1972 aged 15 years. I may have been about 17 when I started to fade for several reasons.
I always had supressed doubts, but some of the main reasons I left were my resistance to pressure to go to the SDA college to become a full time pastor (SDA UK version of Gilead?) The other reason was to lead a more normal lifestyle.
Despite no longer attending Central Hall, and attending several other Protestent denominations, I still believed the SDAs had more right than any other religion - ie the closest to the truth. I only discovered where they were wrong in the past year through studying JWs. In 1972, we were certain that we would not grow old, the end was so near....
I'm glad you are kind about adventists - I have so much love and respect for them, even though I believe they are misguided about many of their doctrines. They are however Christian, unlike JWs. After I left and later married, I gradually all but lost my belief and sat somewhere between agnostic and athiest. That was because I knew the SDAs could not be right, but I believed they were more right than anyone else - so where else could I go? Sound familiar?
It is ironic that I was trying to prove to a JW that he was wrong, and that he should become an SDA if he wanted to be a faithful Christian, led me to understand why both are wrong, for similar reasons.
Not sure why she asks questions about her religion? She can get all the answers from SDAs. In my view one of the problems with both religions is the whole concept of trading proof texts. This is not the way to find truth. Does she want to convert me back to SDA?
I have answered your 1st two questions.
Q3. The SDA teaching is the dead are as if asleep, no consciousness, nothing, until Jesus imminent second coming....
My own belief is that no one knows, and the Bible's teaching on this is not completely clear, some texts appear to support JW & SDA views. Others strongly indicate there is some other state prior to Christ's second coming.
Q4. SDA's believe in the trinity and I believe they teach that Christ is in heaven. Not sure they teach he is judging the world yet, don't think so. I have my own views on these things but it would take a few pages...
I would love to respond further but unsure what your friend wants me to say. Give her my good wishes please.
