"Do you not know from the Word that the Father and the Son are one, that the Father is in the Son, and the Son in the Father? This the Lord plainly says (in John 10:30, and 14:10, 11). If you do not believe this you divide God into two; and when this is done you are unable to think about God otherwise than naturally, sensually, and even materially; and this has been done in the world since the time of the Council of Nice, which introduced the doctrine of three Divine persons from eternity, and thereby turned the church into a theater furnished with painted hangings, where the actors were representing new plays. Who does not know and acknowledge that God is one? If you acknowledge this in heart and spirit, all that you have just said is of itself dissipated, or rebounds into the air like nonsense from the ear of a wise man.
'To sit at the right hand' does not mean to sit at the right hand, like two persons sitting side by side. It means Jehovah God's Divine Omnipotence through the Human that He assumed in the world under the name Jesus Christ. By means of this He is in things last as well as in things first; by means of this He entered and overthrew and subjugated the hells; by means of this He restored order in the heavens; and thus by means of this He redeemed both men and angels, and will continue to redeem for ever. If you consult the Word, and are capable of enlightenment, you will perceive that 'right hand' means here omnipotence, as it does in Isaiah: My hand hath founded the earth, and My right hand hath spanned the heavens (47:13). Jehovah hath sworn by His right hand and by the arm of His strength (62:8). Thy right hand doth hold Me up (Ps. 18:35). Look to the Son that Thou madest strong for Thyself; let Thy hand be for the man of the right hand, for the Son of man whom Thou madest strong for Thyself (Ps. 80:15, 17). From this it is plain how the following is to be understood: The saying of Jehovah to my Lord, Sit Thou at My right hand until I make Thine enemies a footstool for Thy feet. Jehovah shall send the staff of Thy strength out of Zion; rule Thou in the midst of Thine enemies (Ps. 110:1, 2). This whole Psalm treats of the Lord's combat against the hells, and His subjugation of them. As 'the right hand of God' signifies Divine Omnipotence through the Human Form: The Lord says that He is to sit at the right of power (Matt. 26:63, 64) And at the right hand of the power of God" (Luke 22:69).
