I once tried to find the actual origin of the Bible word 'church' using Strong's, several translations, and of course internet search. What I found was a confusing labyrinth of differing notions about the word with no real conclusion that one could settle upon as a good reason to translate ecclesia (or however you want to spell it) as 'church'. I found this astonishing since the Greek word has a simple, straightforward, provable meaning, i.e., a group called out for a special purpose. How easy would it have been to just translate the word into it's common meaning, 'called out'? But it would not have suited the purpose of the 'church'? Same as the real translation of aionios (with different forms) and sheol. hades, gehenna, tartarus would not have been beneficial to real intent of the 'church'. For me, 'the church' is just another fairly easily discernible deception of the Enemy.
Also, I was recently slapped up side the head with the reality that within even the true called-out assembly, only a few (elect) were actually 'overcomers' and would partake of the promises given to the overcomers in the letters to the messengers of the called-out assemblies in Asia. Revelation 2-3. The rest of the people in the 'churches'/ecclesias are obviously NOT overcomers and will not inherit the kingdom and rulership or aionion life. Made me swallow pretty hard. Am I worthy of the kingdom? Have I really been obedient to the Master? To be quite honest, if I were judging me, I'd likely not be one of the elect, at least up until this point. But I now better understand Jesus' and the apostles' continuous call for the diligence and striving of the 'saints'/set apart ones for the prize.
In any case, I, God willing, will not again be hoodwinked by 'the church'. At least not fully deceived, since I'm sure I've still got some vestiges of the false notions in me that were planted there. The delusion is very powerful.
This is just MY personal experience and I don't try to force it on anybody. If one wants to use the word church to describe the ecclesia, makes no difference to me as long as he or she knows what it is truly representing. I just prefer truthful and intelligent use of words. And... I find it outrageous that an entity claiming to be the witness for the Messiah on the earth is representing Him as an Eternal Torturer and is collecting 'tithes' from the 'tribes' to do so. No wonder John was amazed when he saw Her.
Sorry, just got up for the day with two cups of coffee. Zing! Hope everybody has a great day. One day closer!
