The Canonical Epistle, with the Commentaries of Theodore Balsamon and John Zonaras 5Canon V.

But upon those who have used dissimulation like David, who feigned himself to be mad to avoid death, being not mad in reality; and those who have not nakedly written down their denial of the faith, but being in much tribulation, as boys endowed with sagacity and prudence amongst foolish children, have mocked the snares of their enemies, either passing by the altars, or giving a writing, or sending heathen to do sacrifice instead of themselves, even though some of them who have confessed have, as I have heard, pardoned individuals of them, since with the greatest caution they have avoided to touch the fire with their own hands, and to offer incense to the impure demons; yet inasmuch as they escaped the notice of their persecutors by doing this, let a penalty of six months' penance be imposed upon them. For thus will they be the rather profited, meditating upon the prophet's words, and saying, "Unto us a child is born, unto us a Son is given; and the government shall be upon His shoulder: and His name shall be called the Messenger of My mighty counsel." Who, as ye know, when another infant in the sixth month of his conception had preached before His coming repentance for the remission of sins, was himself also conceived to preach repentance. Moreover, we hear both also preaching, in the first place, not only repentance, but the kingdom of heaven, which, as we have learned, is within us; for the word which we believe is near us, in our mouth, and in our heart; which they, being put in remembrance of, will learn to confess with their mouths that Jesus is the Christ; believing in their heart that God hath raised him from the dead, and being as those who hear, that "with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation."
