“Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.”
Matthew 7:21 — Greek Interlinear
Church Fathers on Matthew 7:21
As He had said above that those who have the robe of a good life are yet not to be received because of the impiety of their doctrines; so now on the other hand, He forbids us to participate the faith with those who while they are strong in sound doctrine, destroy it with evil works. For it behoves the servants of God that both their work should be approved by their teaching and their teaching by their works.
Wherein He seems to touch the Jews chiefly who placed every thing in dogmas; as Paul accuses them, 'If thou art called a Jew, and restest in the Law.'
Otherwise; Having taught that the false prophets and the true are to be discerned by their fruits, He now goes on to teach more plainly what are the fruits by which we are to discern the godly from the ungodly teachers.
