“This can be and is a progressive process which may be repeated over time leading to an ongoing evolution of thought and beliefs.”
Sure, but the alternative process is also a progressive process, even if its adherents do not like to admit as much. The difference is, that at some points, the progress is frozen in place by putting some questions “off limits”, and placing them in the category of dogmatic truth, then labeling as heretics anyone who continues to hold a contrary opinion.
Then, the remaining believers can say “we’ve always believed these things”, and if you point out that they hadn’t, they have the fall-back answer of “well, those people were heretics”. It’s all a very nice rhetorical trick, but I don’t think it changes the reality of the situation at all.
We believe that, but people believe it differently -- some posters here, Jehovah's Witnesses will point out texts that prove their point that Jesus was just a good point, others, SEventh Day Adventists will point out texts that He was the first created being but not God, and we have ideas similar to that spouted by posters of the "Messianic Jewish" or Modalist view
then there are many who reject the idea of the Trinity (the Modalists) with varied ideas -- from jehovah's witnesses to Oneness pentecostals to other views
