Yes, you are correct, the word "Ekklesia/church" doesn't appear again until Rev.22:16, which is not supporting your cause. In Chapters 1 thru 3 the word "church" is used 18 times. Within those same chapters you will not find the word "Hagios/Saints." Likewise, from chapter 4 onward, you no longer see the word "Ekklesia/Church" mentioned within the narrative of God's wrath, but outside of it, which you and others ignore. The fact that the word "church" is absent during the narrative of God's wrath and only shows up at the end of the closing of Revelation supports what we have been telling you.
As I said, the gathering of the church takes place at Rev.4:1-2 where that voice that sounds like a trumpet says "come up here." It is a prophetic allusion to the gathering of the church, which God obviously put there for those who recognize it as a prophetic clue and which you obviously can't see.
On the contrary, you try again!
