§663
Creed › … › Article 6: "He Ascended Into Heaven and Is Seated at the Right Hand of the Father"
Henceforth Christ is seated at the right hand of the Father: "By 'the Father's right hand' we understand the glory and honour of divinity, where he who exists as Son of God before all ages, indeed as God, of one being with the Father, is seated bodily after he became incarnate and his flesh was glorified."
