Through Jesus, the promises of God made through the prophecies of old will be fulfilled. “You will learn then that I am the Lord your God.”
Prior to the verses of our gospel for today, Jesus spoke about “the fundamental truth that you cannot leave a man’s soul empty. It is not enough to banish the evil thoughts and the evil habits and the old ways and leave the soul empty. An empty soul is a soul in peril . . . You’ve got to fill a man with something. It is not enough to drive out evil; good must come in . . . The woman who spoke was carried away by a moment of emotion. Jesus pulled her back to reality. The moment of emotion is a fine thing; but the greatest thing is a life of obedience in the routine things of every day. No amount of fine feeling can take the place of faithful doing.” (William Barclay)
The Jewish baby was always suckled by its own mother even up to two or three years. It was a duty that the rabbis reminded them of. When a child was at last weaned, a feast and sacrifice was made in memory of Abraham’s celebration of the time Sarah stopped suckling Isaac. Thus the child was solemnly made a member of the religious community and marked by the seal of God in circumcision for a male child. (Daily Life in Palestine at the time of Christ by Henri Daniel-Rops)
Jesus elevated this sanctity of being marked with the “seal of God” from its ritual roots to one’s commitment to living the faith in God’s word.
