The true love is the Love of Charity, it is the unconditional love that gives without asking for anything in return, it is the love based on friendship with the other, that is, it is not based in the egoistic desire to possess the beloved, in a certain meaning is the contemplative love. To give an example of this, Aristotle tells us about the love that some mothers experience with their children, "love with joy", enjoying with love; this form of love is also given in a similar way when the friendship is very intense (philia or philos in Greek), as Saint Augustine relates in his book Confessions, he speaks to us when he describes the true friendship, of that love with mercy, of "live and wish to die with the friend".
The Bible describes the true love: "Charity is patient, charity is kind, It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no récords of wrongs. 1 Corinthians 13:4-7.
Jesus expresses it in another way in the new commandment: "Love one another. As I have loved you, so you must love one another", John 13:34. The true love is progressive, tends to improvement and to the perfection that is Charity (Agape). This is why true love is a spiritual gift, that is, it is the infused love. The love of Charity, the love of God is the love projected towards the whole creation of God, it is the love to the neighbor, to the animals, to the science, that is why Jesus insists: you must love one another, as I love you.
Love is fundamentally a genre, we love what we desire, not all love is good; there is a false, a bad love, it is the love tinged with concupiscence.
The love directed to the false goods like the money, the fame, generates evils and sufferings and is the origin of the sinful life, Jesus speaks to us of the false happiness and of the 4 curses in the sermon of the mount in Matthew 6: 24-26 .
