Not Every One That Saith, Lord, Lord
Matthew 7:21-23, doing the will, as the early church read it
Jesus ends the Sermon on the Mount with a sobering word: not everyone who calls Him "Lord, Lord" enters the kingdom, "but he that doeth the will of my Father." And to some who prophesied and worked miracles in His name He will say, "I never knew you." The early church read this as the plainest statement that real faith is a thing done, not merely professed, that assurance rests on the obedient, living relationship and not on words, gifts, or even miracles. The Fathers below, with a plain restatement.

Matthew 7:21 · KJVNot 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.
"Let us not therefore think that this belongs to those fruits… when one says to our Lord, 'Lord, Lord,' and thence seems to us to be a good tree; the true fruit spoken of is to do the will of God; whence it follows, 'But who doeth the will of my Father which is in heaven, he shall enter into the kingdom of heaven.'"
St. Augustine"Scripture uses to take words for deeds; according to which the Apostle declares, 'They make confession that they know God, but in works deny him.'"
St. JeromeThe dividing line is not between those who say the right things and those who do not, but between sayers and doers. To call Jesus "Lord" and not do what He says is, in Scripture's own reckoning, to "deny him in works." The "true fruit," Augustine says, is doing the Father's will. Faith that never becomes obedience is not yet the faith that saves.
Matthew 7:22-23 · KJVMany will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
"He says to them, 'I never knew you,' as it were, not at the day of judgment only, but not even then when ye were working miracles. For there are many whom He has now in abhorrence, and yet turns away His wrath before their punishment."
St. John Chrysostom"By this sentence it is given to us to learn, that among men charity and humility, and not mighty works, are to be esteemed… the proof of holiness is not to work miracles, but to love."
St. Gregory the GreatThis is the startling part: people who prophesied, cast out demons, and worked wonders in His name are turned away. Their résumé of spiritual achievements counts for nothing, because, as Chrysostom notes, He "never knew" them, not even while the miracles were happening. The thing that matters is not power or platform but the obedient relationship; Gregory: "the proof of holiness is not to work miracles, but to love." Gifts are no substitute for being known by Him.
Matthew 7:23 · "ye that work iniquity"…depart from me, ye that work iniquity.
"He says not, Who have worked, but 'who work iniquity,' that He should not seem to take away repentance. 'Ye,' that is, who up to the present hour… yet retain the desire of sinning."
St. JeromeEven here the door is not slammed on the penitent. Jerome notices the present tense: not "who once sinned," but "who work iniquity", those still, even now, clinging to the desire to sin. The warning is against a life that keeps choosing wrong while mouthing the right words, not against the sinner who turns back. Repentance is never foreclosed.
Where this lands: faith as a verb
This passage is not a battleground between the traditions, all confess that real faith bears fruit, but it presses hard against any version of the gospel that shrinks faith to a one-time profession or a feeling. The early church read it as the heart of what we might call the synergy of salvation: God's grace is everything, and the response He calls for is not a mere "Lord, Lord" but a doing of His will, the active, obedient, God-enabled "yes" that runs all through Scripture (the blood applied to the doorpost, Rahab staying in the marked house, the seed that bears fruit). To make faith only an inward assent, with no doing, is exactly the flattening this verse rebukes. And assurance, on Jesus' own terms, rests not on our words or our spiritual achievements but on being truly known by Him, in a living relationship that does His will. (See Lord, or Just Savior?, Hebrews 11: the faith that does, the Security of Salvation, and Tested in the Wilderness.)
