7. Today’s Gospel also teaches by this parable that our free will amounts to nothing, since the good seed is sowed only by Christ, and Satan can sow nothing but evil seed; as we also see that the field of itself yields nothing but tares, which the cattle eat, although the field receives them and they make the field green as if they were wheat. In the same way the false Christians among the true Christians are of no use but to feed the world and be food for Satan, and they are so beautifully green and hypocritical, as if they alone were the saints, and hold the place in Christendom as if they were lords there, and the government and highest places belonged to them; and for no other reason than that they glory that they are Christians and are among Christians in the church of Christ, although they see and confess that they live unchristian lives.
8. In that the Savior pictures here also Satan scattering his seed while the people sleep and no one sees who did it, he shows how Satan adorns and disguises himself so that he cannot be taken for Satan. As we experienced when Christianity was planted in the world Satan thrust into its midst false teachers. People securely think here God is enthroned without a rival and Satan is a thousand miles away, and no one sees anything except how they parade the Word, name and work of God. That course proves beautifully effective. But when the wheat springs up, then we see the tares, that is, if we are conscientious with God’s Word and teach faith, we see that it brings forth fruit, then they go about and antagonize it, and wish to be masters of the field and fear lest only wheat grows in the field, and their interests be overlooked.
9. Then the church and pastor marvel; but they are not allowed to pass judgment, and eagerly wish to interpret all for the best, since such persons bear the Christian name. But it is apparent they are tares and evil seed, have strayed from the faith and fallen to trust in works, and think of rooting out the tares. They lament because of it before the Lord, in the heartfelt prayer of their spirit. For the sower of the good seed says again, they should not uproot it, that is, they should have patience, and suffer such blasphemy, and commend all to God; for although the tares hinder the wheat, yet they make it the more beautiful to behold, compared with the tares, as St. Paul also says in 1 Corinthians 11:19: “For there must be false factions among you, that they that are approved may be made manifest among you.” This is sufficient on today’s text.
