We see Jesus saying at Matthew 5:48 (NRSVCE)
"Be perfect, therefore, as your heavenly Father is perfect"
Now, the image of God the Father that the Jewish people had had, before they listened to the teachings of Jesus including the Parable of the Prodigal Son, would be the one at Psalm 103:8-10 (NRSVCE):
" The Lord is merciful and gracious, slow to anger and abounding in steadfast love.He will not always accuse, nor will he keep his anger forever.He does not deal with us according to our sins,nor repay us according to our iniquities.""
That is, God the Father did get angry many a time and punished the Israel occasionally! Could the Jews therefore, treat Him as the role model of perfection? Would not Jesus himself, in human nature and form, make a better candidate as the role model of perfection for the Jews?
My question therefore is: Why did Jesus project God the Father as the role model of perfection? Does the Catholic Church offer any comments on the issue?
