Ambrose of Milan — as excerpted in the Catena Aurea on Luke 15:11-16

“Now you see that the Divine patrimony is given to them that seek; nor think it wrong in the father that he gave it to the younger, for no age is weak in the kingdom of God; faith is not weighed down by years. He at least counted himself sufficient who asked, And I wish he had not departed from his father, nor had had the hindrance of age. For it follows, And not many days after, the younger son gathered all together, and took his journey into a far country.”
