Theophylact of Ohrid — as excerpted in the Catena Aurea on John 19:23-24

“The garment without seam denotes the body of Christ, which was woven from above; for the Holy Ghost came upon the Virgin, and the power of the Highest overshadowed her. This holy body of Christ then is indivisible: for though it be distributed for every one to partake of, and to sanctify the soul and body of each one individually, yet it subsists in all wholly and indivisibly. The world consisting of four elements, the garments of Christ must be understood to represent the visible creation, which the devils divide amongst themselves, as often as they deliver to death the word of God which dwelleth in us, and by worldly allurements bring us over to their side.”
