▼98:5 Adore his footstool: The ark of the covenant was called, in the Old Testament, God’s footstool: over which he was understood to sit, on his propitiatory, or mercy seat, as on a throne, between the wings of the cherubims, in the sanctuary: to which the children of Israel paid a great veneration. But as this psalm evidently relates to Christ, and the New Testament, where the ark has no place, the holy fathers understand this text, of the worship paid by the church to the body and blood of Christ in the sacred mysteries: inasmuch as the humanity of Christ is, as it were, the footstool of the divinity. So St. Ambrose, L. 3. De Spiritu Sancto, c. 12. And St. Augustine upon this psalm.(Challoner)
