Re:
“they assembled on the first day of the week to break bread (the Lord’s supper)” -— “they assembled” is a Finite, Indicative Continuous VERB; ‘synehgmenohn’ is a Perfect Participle: NO Verb whatsoever; it does not describe an action but a circumstance or condition. It is more Adjectival than Adverbial seeing it describes the disciples as “having been assembling STILL AFTER having HAD been assembling BEFORE” -— there you are! Now I have got it right! Every word and every concept of this IS CONTAINED IN the Perfect Participle ‘synehgmenohn’. Only then, comes the VERB of the only Sentence of the passage Act20:7 into play -— “dielegeto” Paul “conversed”. Please read book 3/2 ‘Troas’. (+-1970)
