Romans 14 is proof that in the text, some verses are indicative, some pertinent, some relative, and some imperative, romans 14 is very pertinent, to
their situation, where there was fighting with jew and greek, in the house churches, so pertinent appies to
that situation, and the weak people addressed, 14:1, 15:1, the weak, is how one should approach the text knowing the history, and the present situation, and who is addressed.
While talking to an elder, Tim, in 1 Tim 4, there he talks a different language, to a fellow teracher, doctrine of demons, food stuff.
So again, the narrative is filled with diversity, that if read with a proper understanding of the context and history, it is easier to understand.
