Tractate 41
10. The first freedom, then, is to be without crimes. And so when the Apostle Paul chose either presbyters or deacons to be ordained, and when anyone is to be ordained to take charge of a church, he does not say, If anyone is without sin. For if he were to say this, every person would be rejected, no one would be ordained. But he says, "If anyone is without crime", such as homicide, adultery, and uncleanness of fornication, theft, fraud, sacrilege, and other things of this sort. When a person begins not to have these – and no Christian ought to have these – he begins to lift his head to freedom; but his freedom has only been begun, it has not been brought to perfection.
