Ambrosiaster

God is no respecter of persons. Even Saul and Judas had been good at one time. How could someone who was not good have a share in the Savior's ministry? In the plan of God it was decided that we would be considered worthy for the time for which he was chosen. It is no wonder that these men were considered good, because all nature is good and no substance is evil, but rather transgression, which arises from the will.

Now the Jews deserved to be punished all the more, because they did not know Christ the Creator, either by nature or by the law. He is our head. At God's behest we recognize Him as the author of our life. And to this gift God adds the Gentiles, indiciating that we have been saved by the grace of God.

Paul also says that the Jews did not believe in Christ because they were ignorant (Rom. 10:3). They wanted to show their zeal for God, but not knowing his will or plan, they acted against him even though they claimed to be defending him. Paul says of them that it was not out of malice or envy but out of ignorance that they did not accept Christ. Not realizing that this was the Christ whom God had promised, they said they were waiting for someone else. Preferring the righteousness which they had from the law over him who is the righteousness of God in faith.
