re: If B16 is a heretic, then the only logical position is sedevacantism.

Who has the authority and who proves that he is a heretic? That is the question. We have no authority. Pope Honorius was excommunicated 45 years after he died, by another pope.

re: What is unclear about this statement?:

"For those who are not formally and visibly members of the Church, salvation in Christ is accessible by virtue of a grace which, while having a mysterious relationship to the Church, does not make them formally part of the Church, but enlightens them in a way which is accommodated to their spiritual and material situation".

That “salvation in Christ is accessible by virtue of a grace", IS CORRECT, "salvation is accesible by grace". Without grace there is no turning to God for anyone, Catholic or otherwise. Accesible does not mean that one is saved, it just means that it is available. This does not say that Protestants can be saved outside of the Church, which would be a heresy.

Apparently you DO have the authority! You, throughout this thread, have boldly brought forth an interpretation of EENS which is in conflict with current Church teaching and is in conflict with the interpretation of the vast majority of Catholics who frequent this forum. With that authority, you should not have any problem labeling a teaching as heretical, without regard to the source. OK, it may not be your place to formally declare someone a heretic, but you can call a teaching heretical, can't you?

"For those who are not formally and visibly members of the Church, salvation in Christ is accessible"

Is this statement heretical?
