3 I had rather then, O Emperor, have fellowship with you in good than in evil, and therefore the silence of the priest ought to displease your Clemency, and his freedom to please you. For you are involved in the risk of my silence, but are aided by the benefit of my freedom. I am not, then, officiously intruding in things where I ought not, nor interfering in the affairs of others. I am obeying the commands of God. And I do this first of all out of love for you, good-will toward you, and desire of preserving your well-doing.
If I am not believed in this, or am forbidden to act on this feeling, I speak in very truth for fear of offending God. For if my peril would set you free, I would patiently offer myself for you, though not willingly, for I had rather that without my peril you might be acceptable to God and glorious. But if the guilt of silence and dissimulation on my part would both weigh me down and not set you free, I had rather that you should think me too importunate, than useless and base. Since it is written, as the holy Apostle Paul says, whose teaching you cannot controvert: “Be instant, in season, out of season, reprove, entreat, rebuke with all patience and doctrine.”
