Origen: "Jesus confirms all of the beatitudes"
"Jesus confirms all of the beatitudes he speaks in the Gospel, and he justifies his teaching though his own example. “Blessed are the meek” is what he says of himself. “Learn of me, for I am meek.” “Blessed are the peacemakers.” Who is a peacemaker like my Lord Jesus, who is our peace, who made enmity to cease and destroyed it in his flesh? “Blessed are they who suffer persecution for righteousness’ sake.” No one more than the Lord Jesus, who was crucified for our sins, endured persecution for righteousness’ sake. The Lord, then, displays all the beatitudes as being realized in himself. Conforming to that which he said, “Blessed are those who weep,” he himself wept over Jerusalem, to lay the foundation of this beatitude also." ( Homilies on Luke 38.1-2, SC 87, ed. Crouzel, Fournier, Périchon, p. 443 quoted from Dale C. Allison, Studies in Matthew: Interpretation Past and Present (Baker Academics 2005), p. 150)
