Nope. But I won't pressure you further to find verses that aren't there.
What of this "secret" info, though?
Jesus promised his Holy Spirit to guide his church. I take him at his word. You are under no obligation to do so. Peace be with you.
Not so fast Must we repeat,
other than what was openly and widely taught, much generally covered in the Synoptic Gospels and the Epistles...
Some of it is pure blarney. (which is quite grevious, being as it is so mixed up with actual Truth)
The fleshly reasonings & imaginations of men, dribbling out over time, over many centuries, "developing", or as those Catholics whom do know the difficult history beyond the usual apologetic put it, "unpacking".
Claiming it "was always there" (but without much credible framework) it just needed to be unpacked, so we could see what's really inside it.
It is quite interesting that this "unpacking' claim is utilized frequently in regards to those questionable, controversial dogmas, which then are of course, said to originate from Christ or the Apostles, but only by oral tradition, much of the time as I've previously noted, only surfacing two-three-four hundred years and more, after the time of Christ.
That is why I follow the lead of another, in calling it "the fuzzy infallibles" whenever "tradition" is relied upon as proof-of-concept for those dogmas not much found in the Word.
You may not realize it, but you have certainly delivered on your end. The typical apologetic. Which sounds good at first, but when poked at a bit begins to sadly deflate...
But not to worry overly much, eh? We still can rest in the assurance that Jesus was and is who He said He is, as deeply mysterious to us as that may be.
