Augustine of Hippo, on Matt 7:21

“Not every one that saith to me, Lord, Lord, shall enter into the kingdom of heaven: but he that doth the will of my Father who is in heaven, he shall enter into the kingdom of heaven.”

“(Serm. in Mont. ii. 24.) For even in the very name of Christ we must be on our guard against heretics, and all that understand amiss and love this world, that we may not be deceived, and therefore He says, Not every one that saith unto me, Lord, Lord. But it may fairly create a difficulty how this is to be reconciled with that of the Apostle, No man can say that Jesus is the Lord, but by the Holy Ghost. (1 Cor. 12:3.) For we cannot say that those who are not to enter into the kingdom of heaven have the Holy Spirit. But the Apostle uses the word ‘say,’ to express the will and understanding of him that says it. He only properly says a thing, who by the sound of his voice expresses his will and purpose. But the Lord uses the word in its ordinary sense, for he seems to say who neither wishes nor understands what he says.”
