SCRIPTURE COMMENTARY #101
And Jesus also was invited, and his disciples, to the marriage. (John 2:2)
MATRIMONY: By His presence at the marriage-feast of Cana Jesus honored and sanctified marriage, which had already been instituted in Paradise. It was always from the beginning an indissoluble contract sanctioned by God. But now it is to become even more sacred and indissoluble. For Christ is going to make it a Sacrament and a symbol of His own union with the Church. Hence He comes here with the first fruits of His Church to celebrate, so to speak, a double marriage-feast, that of Himself and His Church, and that of the bridegroom and bride.
