to which I claim to belong, as a citizen of the Kingdom of Christ, which is not of this world..
"πανηγυρει και εκκλησια πρωτοτοκων εν ουρανοις απογεγραμμενων" (Heb. 12:23a Textus Receptus)
It is to a local Induction and Training Center with a particular local title (there are many such, globally) to which I report to continue stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers. The regenerated constituents are presumed with confidence to pass on to the Lord's Presence in the Paradise of Heaven upon graduation from the earthly discipleship phase.
That is the appropriate Assembly, founded upon The Lord Jesus Christ, to which the spiritually regenerate one belongs. Nowhere in the Bible in any plenarily inspired infallible properly and faithfully preserved and translated text do I find a locally instituted, enrolled, regularly summoned, and corporately gathered Christian Company with the adjective "Catholic" included in its title.

The priest doesn’t comprehend that Jesus did not establish an institution, He established ‘a body’ of believers. GOD knows that only pride benefits from joining an org, like Roman Catholiciism. That is why HE did not establish an org.
What you said.
I am assuming that both you and I are members of this Church, in this sense.
