11 Against people of this kind the Lord cries; from these He restrains and recalls His erring people, saying, “Hearken not unto the words of the false prophets; for the visions of their hearts deceive them. They speak, but not out of the mouth of the Lord. They say to those who cast away the word of God, You shall have peace, and every one that walks after his own will. Every one who walks in the error of his heart, no evil shall come upon him. I have not spoken to them, yet they prophesied.
If they had stood on my foundation (substantia, ὑποστα'σει), and had heard my words, and taught my people, I would have turned them from their evil thoughts.” Again, the Lord points out and designates these same, saying, “They have forsaken me, the fountain of living waters, and have hewed them out broken cisterns which can hold no water.” Although there can be no other baptism but one, they think that they can baptize; although they forsake the fountain of life, they promise the grace of living and saving water.
Men are not washed among them, but rather are made foul; nor are sins purged away, but are even accumulated. Such a nativity does not generate sons to God, but to the devil. By a falsehood they are born, and they do not receive the promises of truth. Begotten of perfidy, they lose the grace of faith. They cannot attain to the reward of peace, since they have broken the Lord's peace with the madness of discord.
