We hold
moreover, that Christ sits in the body at the right hand of God the Father, but
we do not hold that the right hand of the Father is actual place. For how could
He that is uncircumscribed have a right hand limited by place? Right hands and
left hands belong to what is circumscribed. But we understand the right hand of
the Father to be the glory and honour of the Godhead in which the Son of God
who existed as God before the ages, and is of like essence to the Father, and
in the end became flesh, has a seat in the body, His flesh sharing in the
glory. For He along with His flesh is adored with one adoration by all
creation. (An Exact Exposition of the Orthodox Faith, Book IV, Chapter II [NPNF2
9:74])
For a Latter-day Saint understanding (and I would say, biblical-exegetical reading, too) of "right hand of God" and Acts 7:55-56, see:
