Apostolic Constitutions, Book VI 21
1But blessed are your eyes, for they see; and your ears, for they hear. Yours, I say, who have believed in the one God, not by necessity, but by a sound understanding, in obedience to Him that called you. For you are released from the bonds, and freed from the servitude. For says He: I call you no longer servants, but friends; for all things that I have heard of my Father have I made known unto you. For to them that would not see nor hear, not for the want of those senses, but for the excess of their wickedness, I gave statutes that were not good, and judgments whereby they would not live; they are looked upon as not good, as burnings and a sword, and medicines are esteemed enemies by the sick, and impossible to be observed on account of their obstinacy: whence also they brought death upon them being not obeyed.
