But go ahead, pick and chose what portions of Scripture you want to believe and what portions you want to pretend aren't there. Use whichever verses you like as you see fit for your own personal interpretation of Scripture and your own personal religion. In doing so you're worshiping Self and not God incarnate as Christ. But go ahead, continue to claim that Christ was either a liar or just plain too stupid to say that He really meant since that's what is required for you to espouse the "Invisible Church", "Sola Myselfa", "Faith in Myself Alone", rubbish.
Considering that intrinsic to such a claim is Christ allowing what you say is heresy to be accepted throughout the world as Christianity, the Gates of Hell prevailed against His Church in spite of His promise to the contrary. Yet another instance of calling Jesus Christ the incarnate Son of God Almighty, God from God, a liar. There's no way I could ever agree with the fantasy you described given the numerous times you have to call Christ a liar in order to accept it. Anyone who wants to, though, is free to call Jesus Christ a liar as often as they like in order to accept the " ... despite their heretical Church" fantasy.
So did the Angel describing the seven heads of the Beast of Revelation.
