May be able to comprehend with all saints what is the breadth, and length, and depth, and height;
All Commentaries on Ephesians 3:18 Go To Ephesians 3
Gregory of Nyssa
AD 394
The divine mind of the apostle did not imagine this fourfold figure of the cross to no purpose. He knew that this figure, which is divided into four segments from the common center, represents the power and providence of the one displayed upon it. This dimensionality runs through all things. For this reason he calls each of four projections by its own name. By the height he means what is above, by the depth the underworld, by the length and breadth the intermediate domain which is under the control of his allgoverning power. Hence the worship of the cross is viewed in relation to the fourfold figure of the cross. The heavenly order is symbolically paying its devotion to the Lord in the upper part, the cosmic order in the middle part and even the infernal order in the lower part. .
