And he said, A certain man had two sons. — We enter here on one of the parables which are not only peculiar to St. Luke’s Gospel, but have something of a different character, as giving more than those we find in the other Gospels, the incidents of a story of common daily life. As with the Good Samaritan, it seems open to us to believe that it rested on a substratum of facts that had actually occurred. It is obvious that in the then social state of Palestine, brought into contact as the Jews were with the great cities of the Roman empire, such a history as that here recorded must have been but too painfully familiar.
In the immediate application of the parable, the father is the great Father of the souls of men; the elder son represents the respectably religious Pharisees; the younger stands for the class of publicans and sinners. In its subsequent developments it applies to the two types of character which answers to these in any age or country. On a wider scale, but with a less close parallelism, the elder son may stand for Israel according to the flesh; the younger for the whole heathen world. Looking back to the genealogies of Genesis 5:10; Genesis 9:18, and even (according to the true construction of the words) Genesis 10:21, they correspond respectively to the descendants of Shem and those of Japheth. It is obvious from the whole structure of the parable that the elder son cannot represent the unfallen part of God’s creation; and, so far as it goes, this tells against that interpretation of the ninety and nine sheep, or the nine pieces of silver.
