I think I know what you mean, But debate is allowed.You're asking in an online forum if excessive interpretation can lead to division?
What I just want to express is that the proposal of a viewpoint should be supported by reasonable biblical scriptures.
There is also need for a mind that simply obeys the exact words of the Bible scriptures as a child.
So it seems to me that most of the differences come from over-interpreting the original words of the Bible text,
People usually pick one up and throw one away like monkeys carrying corn.
Everyone should have a basic and simple overall concept of acknowledging the original text in the Bible.
The Gospel of Luke
21:14 Settle it therefore in your hearts, not to meditate before what ye shall answer:
21:15 For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist.
