Jesus' preaching, in the Gospel of Matthew, begins with the Sermon on the Mount where he teaches the eight Beatitudes (Matthew 5:1-12). After this Jesus expresses, in the scriptures his most important teachings about the faith and synthesizes the ethics and morals of the gospels: denounces heresies, the teaching of the error: the law of talion, "You have heard that it was said that it was said, "Eye for eye, and tooth for tooth" Matthew 5:38; and a heresy about love: "Love your neighbor and hate your enemy", in Matthew 5:43.
An then he opposes the heresies to his teaching about wisdom: "But I tell you, love your enemies and pray for those who persecute you" Matthew 5:44; "No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money" Matthew 6:24; the definition of the good and the spiritual gift of righteousness, "Do to others what you would have them do to you" in Matthew 7:12.
After which he does some healings and institutes the disciples in the mission of the kingdom of God. Finally summarizes his actions and teachings: "Yet wisdom is justified by her deeds" Matthew 11:19
Wisdom is the science of truth, substance and ultimate causes (Aristotle), it is the knowledge of the correct means to live. The wisdom has two characteristics is precision and accuracy. Wisdom is a perfection, that is it cannot be superate or overcome.
And this wisdom is concretized in other perfections, in works of mercy and piety, of which Jesus is the example. For this, wisdom is justified. And this is very important, because wisdom is opposed to the virtue, justice is a form of error in the case of the Law of Talion; wisdom also opposes sin; and even to the Law of Moses: "Let any one of you who is without sin be the first to throw a stone at her", John 8:7.
