For both he that sanctifieth [Jesus] and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren. (Heb 2:11)
This passage is yet another instance of a problematic passage for Trinitarian Christology from Hebrews. The underlying Greek of the phrase, "all of one" is ἐξ ἑνὸς πάντες, meaning "all from one [source]," with the source being the Father. Notice that the author of Hebrews is not discussing the human nature of Jesus per the Hypostatic Union; instead, as with Heb 1:3, the totality of the (exalted/post-ascension) Jesus is in view, and Jesus, as with humanity, are said to have the same source. This fits LDS Christology and anthropology, as we are all the spirit sons and daughters of God (cf. my discussion refuting the charge of Arianism and also Job 1:6 and its implications for LDS theology), Christ Himself included, and we are all dependent upon the singular person of the Father for life, again including Christ (per John 5:26), showing that the Father alone is autotheos. Furthermore, it supports LDS theology that we are all the spiritual sons and daughters of God (the Father), Jesus Himself included, showing a propriety to Latter-day Saints calling the Lord Jesus Christ our "[elder] brother."
As with many theological issues, it is The Church of Jesus Christ of Latter-day Saints that reflects true "Biblical Christianity," in this instance, the true Biblical Jesus.
