In 1 Moses, while Adam and Eve are upon the earth, the Ruach HaKodesh, or Spirit of God is identified at the Spirit of YHVH. This may be the pre-mortal Jesus Christ, or another name for the Holy Spirit, or the angel of YHVH. We do not know at this point. It may be reasoned that if Adam is Michel, and Michel is the Holy Spirit then the Holy Spirit could not be on the earth while Adam lived in the flesh, however this is conjecture.
The Spirit of YHVH may also merely be another term for the Holy Spirit. In 1 Nephi 3:38 RAV, 11:1b Nephi is “caught away in the Spirit of the Lord... into an exceeding high mountain.” This appears to be a vision and the being with him the Holy Spirit. This indicates that this term may be used both for the
pre-mortal Jesus Christ and the Holy Ghost. At other times the Spirit of YHVH seems to be the light of Christ, such as when the Holy Spirit falls upon the Nephites (Mosiah 2:5 RAV, 4:3a OPV).
See 1 Moses 6:22-24, 9:16; 2 Moses 1:2; Isaiah 11:2 (2 Nephi 9:117 RAV, 21:2 OPV); 1 Nephi 1:11a RAV, 1:12 OPV, 2:21-25 RAV, 7:14-15b OPV, 3:37-256 RAV, 11-14 OPV; Mosiah 3:3 RAV, 5:2b OPV; see also Ruach HaKodesh, Shekinah.
