16th Sunday of Ordinary Time, Year A

 This Sunday the Church gives us another parable of sowing seeds (Matthew 13: 24-43), this one dealing with the good seed and the weeds, which the enemy sows. Here is a wonderful exposition on it from Pope Francis, given in 2014:

The teaching of the parable is twofold. First of all, it tells that the evil in the world comes not from God but from his enemy, the evil one. It is curious that the evil one goes at night to sow weed, in the dark, in confusion; he goes where there is no light to sow weed. This enemy is astute: he sows evil in the middle of good, thus it is impossible for us men to distinctly separate them; but God, in the end, will be able to do so.
And here we arrive at the second theme: the juxtaposition of the impatience of the servants and the patient waiting of the field owner, who represents God. At times we are in a great hurry to judge, to categorize, to put the good here, the bad there....

But remember the prayer of that self-righteous man: “God, I thank you that I am good, that I am not like other men, malicious” (cf. Lk 18:11-12). God, however, knows how to wait. With patience and mercy he gazes into the “field” of life of every person; he sees much better than we do the filth and the evil, but he also sees the seeds of good and waits with trust for them to grow. God is patient, he knows how to wait. This is so beautiful: our God is a patient father, who always waits for us and waits with his heart in hand to welcome us, to forgive us. He always forgives us if we go to him.... 

In the end, in fact, evil will be removed and eliminated: at the time of harvest, that is, of judgment, the harvesters will follow the orders of the field owner, separating the weed to burn it (cf. Mt 13:30). On the day of the final harvest, the judge will be Jesus, He who has sown good grain in the world and who himself became the “grain of wheat”, who died and rose. In the end we will all be judged by the same measure with which we have judged: the mercy we have shown to others will also be shown to us. Let us ask Our Lady, our Mother, to help us to grow in patience, in hope and in mercy with all brothers and sisters.
