Jesus teach us a famous heresy: "Love your neighbor and hate your enemy" in Matthew 5:43, to contrast it with his teaching about the love for the enemies: "Love your enemies and pray for those who persecute you", Matthew 5:44. Heresy means teaching of the error.
This explanation in Matthew 5:44, is the correct teaching because the love of charity, the love of God, is the love projected to the whole creation of God, and this is the love for the nature, the love for the animals. The true love is expansive.
In psychology, we have to understand that we hate what we fear. Fear and hate are complementary emotions; they are passions and psychological imperfections, "God is love without passions" (Thomas Aquinas, Summa Theologiae).
The first epistle of John explains: "There is no fear in love, but perfect love casts out fear because fear has to do with punishment" 1 John 4:18.
When Jesus speaks to us about the love of enemies, he is saying that we should not hate them. Hate does not let us think coldly and leads the mind to error and failure. And Jesus adds: "pray for those who persecute you", Jesus referes here to benignity, that is to say, to be tolerant with evil and to endure the punishment: "charity forgives everything".
With this teaching in the Gospel of Saint Matthew, Jesus warns us about the danger of heresies, heresies hide their true goal: the oppression. There are no "cute lies", the lie is always ugly. Because it is to swallow something that sooner or later will make you feel bad.
I will give as an example my personal case as a writer, I live in a country, Argentina, with the same resources as Canada and the United States. And everyone asks how it can be that a country with so many natural resources has so much poverty.
Those who best guess the answer say that it is an educational problem, but they do not make any more precision about it. The answer is simple, Argentina like the rest of the Latin American and Central American countries are poor because they are oppressed by heresies, and this is the teaching of error. Education systems in poor countries are permeable to the teaching of error, in poor countries, there is no "work ethics".
The concept of heresy is an ethical concept: we are precise and exact, or we fail. Where wisdom is taught wealth is generated, where heresy is transmitted (teaching of the error) poverty is created. We choose between "wisdom" or "heresy".
