Study material is just that, study material. It is not required reading. However, the book "Mormon Doctrine" is good study material and I'd recommend it. The Church didn't assign Bruce R. McConkie to create it, it was his own work.

The church didn't assign the apostle Paul to write his letters, either...doesn't make them less than authoritative in ANY way.

Very lame explanation of what your "apostles" FORMALLY & PUBLICLY communicate on Mormon doctrine!

While this is true; it was quite FAIRLDS-like.

"The church didn't assign the apostle Paul to write his letters, either...doesn't make them less than authoritative in ANY way."

Paul's letters were directed to specific people in the Church in order to instruct and correct them. So yes, they were official and authoritative.

"Very lame explanation of what your "apostles" FORMALLY & PUBLICLY communicate on Mormon doctrine!"

No surprise that you would have this opinion. You have proven more times than can be counted to view the truth as "lame".
