This is meant generally to everybody.
The danger in picking and choosing scriptures to form one’s beliefs on his very big and cannot be understated. That very thing is behind every erroneous teaching found in Christian religions today. I won’t go into specific examples because that would only invite debate with hard feelings all around. I will respectfully point out that selective use of scriptures as a basis for dogma goes back to the very first Council at Nicea in the fourth century.
In the 19th century, though, one-half of the Adventists present for the Great Disappointment, as some still call it, in 1844 chose to use actually look up all the scriptures in any way bearing on biblical topics and only articulate an understanding after doing that and exhaustively looking up all occurrences of keywords in those scriptures for the same purpose as well. If you would like to know why that last just look up the Hebrew word “nephesh” (soul) sometimes in a lexicon and it will become very clear why they did that. What they learned would surprise most and is why Satan has worked hard since to undo the results of their labors. Sadly one of his efforts that is to continue in the errors of William Miller, has been very successful in that effort of his.
I am not a Seventh-day Adventist and they would see me as in the part of the movement they still derisively still call the “Second Day” Adventists though that isn’t entirely correct either.
While laborious, that is the best way to figure out what the Bible teaches in my view. One irony is that I sometimes get accused of cherry-picking scripture by folks at times.
You could well be right about that, though I personally think that it goes back much further than that. The Nicene council did serve an important purpose at the time (condemning Arianism) but some ill came from it as well as you pointed out.
One could argue that selective scripture misreading goes all the way back to the dawn of Christianity itself. You can find numerous examples of the Pharisees doing this as they opposed Jesus, and many early church Christians themselves were guilty of it (as I often point out, is why many of the New Testament epistles were written in the first place).
