St. John of Damascus, traditionally the last of the Church Fathers, explains what we mean when we say that Christ sits “at the right hand of the Father”: not that God the Father has literal hands, but that God the Son shares the Father’s glory.
We also believe that Christ sits in the body at the right hand of God the Father. But we do not believe that “the right hand of the Father” is actually a place. For how could he who is infinite have a right hand limited by place? Right hands and left hands belong to what is finite.
But we understand the right hand of the Father to be the glory and honor of the Godhead in which the Son of God, who existed as God before the ages, and is of one being with 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.
