Some of the posts express view which may be regarded as either subjective or speculative. If.............. then.......... may ...... or may not.............. etc., etc.
May I therefore add another subjective view, and a speculative one too? Familiarity with the Greek koine and/or Slavonic is an asset, indeed as was familiarity with the Latin too in past times, and maybe even up to the present day. The venecular too has the benefit of presenting a teaching function, more readily accessible, along with the icons and symbolism of the layout of the church, etc. Each brings its own gift for those who are attentive, but what may touch a closed heart?
