Paul Thomas (personal communication, 5 December 2003) points out that the pronoun I is in the wrong place according to the traditional rule of grammar that places the I pronoun at the end of a conjunctive noun phrase. Of course, the order here in 3 Nephi 11:36 follows the typical trinitarian order, as elsewhere in the text, including these two in this same chapter:
Even so, the trinitarian word order is not always followed in the Book of Mormon text:
Here in 3 Nephi 11:36, the critical text will maintain the word order of all the textual sources, “for the Father and I and the Holy Ghost are one”.
David Calabro points out (personal communication) that the Book of Mormon has eight examples where the subject pronoun I comes first in a conjunctive subject, as in these examples:
The King James Bible also has many similar examples, such as these instances that parallel the preceding Book of Mormon examples:
The order of the nouns in the King James text follows the order in the original languages (Hebrew for the Old Testament examples, Greek for the New Testament). From this perspective, the word order in 3 Nephi 11:36 is definitely unusual, yet its trinitarian order seems to be fully intended.
Summary: Maintain in 3 Nephi 11:36 the expected trinitarian order, with Christ (here represented by the pronoun I ) coming second.
