It’s no more “private” than you saying the opposite is private. We’re all talking pretty openly here ... :-) ...
The Bible speaks pretty clearly and forthrightly about the subject ... so with the very same verses ... you’ve got someone saying he has brothers and someone else saying he does not.
The ones who say he does not have brothers don’t match up to what the Bible says. They have to “explain further” to let people know why they can’t believe what the Bible says, and thus explain how it means something different than what it says ... LOL ...
What you’ve got going on here is a “theology” that you don’t want to go against ... :-) ...
Speaking of a "theology that you don’t want to go against," you wrote "The Jews his brethren in race rejected him,"
Are you like other antiCatholics who exclude "The Jews his brethren in race" from being covered as the least of these my brethren in the Parable of the Sheep and Goats in Matthew ?
Here’s a short radio segment from The Berean Call, with Dave Hunt and T.A. McMahon (about thirteen minutes) ...

Dave Hunt is dead now, but this was from 2000, I believe. T.A. McMahon is still with the ministry, The Berean Call.
Do you mean like the modernists that have broken with almost two millennia to try to make the blessed mother of "God with us" conform to an image they can recognize in their own modern and evolving theologies ?
