I do have one bone to pick with you on another topic. You said, "...your organization, which is but a piece of a split, is at least sometimes telling me that I can’t be a Christian."
If by "your organization" you mean the Catholic Church, she has never said that anybody can't be a Christian.
You can probably find dubious theological opinions of that tendency, and sometimes even from the clergy (Fr. Leonard Feeney was excommunicated for saying that in 1953, and was reconciled to the Church before his death only because he was believed to be non compos mentis -- "bless his heart, he wuz tetched in th' head",- Mrs. Don-o translation.)
... but that would not be the teaching of the Church.
I’m glad if that’s so... I understand that most modern Roman Catholic takes are that the Roman organization in some sense encompasses the others. I’m not going to complain about such a claim if it wishes to make it, because it is “almost” coterminous with the notion of “invisible church” that evangelicals generally espouse. If you’re a believer upon Him, it doesn’t matter if you are in Rome or Timbuktu or Nashville, you are part of that church. In heaven there aren’t any Roman Catholic or Baptist or Orthodox or Methodist, etc. seats. They are all permanently adopted sons and daughters of the Savior. The return of the Lord would show the believers still on earth how He wants them to coalesce, and with even a pope bowing down to Him there aren’t going to be any institutional pride problems any more. If a literal rapture happens this will be new believers, and ones who suffered through a nasty tribulation to boot.
